What is an IR Illuminator - and Who Needs One?

best ir illuminator for night vision

All night vision optics require some amount of ambient light or IR light to function. While ambient light is visible to humans as well as the prey in hunting, it is not widely used as it can alert the animal. Infrared light is invisible to the human eye but acts as a flashlight for night vision scopes. 

IR has a longer wavelength than visible light and is therefore detected only by the scope and not by the animal or other humans.

An IR laser and illuminator emits the IR light that the scope then uses to observe the field and make it visible to the human eye.

Anyone who uses night vision scopes for hunting, security purposes, or for surveillance would need an IR laser and illuminator.

Some scopes have built-in IR lasers and illuminators, but most don’t. Therefore, in order to be able to see in the dark via a night vision optic, the user needs an IR laser and illuminator.

Our Review

night vision illuminator

Oftentimes, a simple design improvement makes a product much more user-friendly. The FANDYFIRE 940nm IR Flashlight illuminator has a solid and sturdy aluminum alloy construction.

This makes it resistant to occasional bumps and hits encountered as a result of operational abuse. Not only that but since the aluminum alloy is also resistant to corrosion, users are able to use the illuminator in rainy and snowy weather as well.

A beam of 940nm is emitted from a single LED source from the illuminator. The beam is capable of traveling up t0 20-50 meters. The use of a convex optical lens produces a concentrated and focused beam, which illuminates the area much better than a dispersed beam.

One of the best things about this illuminator is that you can zoom in or out of the head section. When zoomed in, it achieves a more concentrated light beam, and when zoomed out, you get a floodlight effect on a limited area in the field.

Hunters or surveillance personnel often have to hold multiple objects at a time. Therefore, gadgets with ergonomic designs that are easy to hold prove to be very useful. This illuminator, in addition to being lightweight, has an anti-slip body. There is also a lanyard that you can use to hang the illuminator from the arm.

To charge the device, all you have to do is connect it to a power source. Rechargeable batteries are not included in the package, and you will have to buy them separately. There is a single power button located at the tail.

Issues and Limitations

The range of the beam emitted by this illuminator is quite limited. With a distance coverage of up to 50 meters and a beam diameter of 1.1 inches, you can only use the illuminator for short-distance viewing. Moreover, the short range might limit its use with Gen 1 scopes.

Bottom Line

Those looking for an illuminator to use with short-range night vision scopes will find this model quite useful. It has a user-friendly layout and valuable features like the zooming head. All in all, this is a decent deal for the buck.

Buying Guide: How to Select the Best IR Illuminator

The choice of the best IR illuminator differs from person to person. However, there are a few elements that you should look at in order to ensure that you get the best deal for your needs. Let’s take a look at these elements.

Choose the Right Model for Night Scope Generation

best ir illuminator for hunting

Night scopes come in different generations. Generation 1-night scopes are considered to be the most dedicated scopes with high performance.

The illuminator you buy should be compatible with the generation of your night vision scope; otherwise, it would be a lost investment. IR illuminators and lasers for Gen1 scopes are also pricier than the rest.

Look for Multiple Scope Compatibility

If you use more than one type of night vision scope, you should look for an illuminator compatible with most of your scopes.

This way, you will not only save money and enhance the working of multiple scopes at the same time but will also have a space-saving solution where one illuminator is easier to carry than multiple illuminators.

Get Warrantied Products

With gadgets like IR illuminators and lasers, it is always a good idea to get warrantied products. This is because often these products are quite expensive and demand a considerable investment.

They are used under harsh conditions and receive some degree of operational abuse. Under such circumstances, it is best to buy warrantied products where you can claim repair or replacement if the product does not perform as advertised.


Specifications: What is a Good IR Illuminator

best ir illuminator for night vision

As we have discussed already, the right illuminator varies from user to user. There is no single illuminator that could satisfy the needs of all users.

But, there are a few basic features that everyone should consider. These features help you decide the right product according to your requirements and should be duly considered before making a purchase. 

Illumination Range

Arguably, the most important feature to consider is the illumination range of the IR illuminator. As the name suggests, the illumination range refers to the distance that the beam emitted from the illuminator can travel.

This range decides how far you can see with a certain illuminator. For small-range hunting like backyard or small hunting grounds, an illuminator that could see anywhere between 30 and 50 meters would suffice. Such illuminators are usually used for hunting down troublesome wild boars, varmints, and rodents.

For medium-range shooting, one should opt for an illuminator with a range between 100 and 200 meters. Usually, deer hunters use illuminators within this range.

However, for game hunting on larger and expanded grounds, a medium-range illuminator will not suffice. You will have to invest in an illuminator with a greater range of 200-350 meters.

Weather Resistance

Hunting gadgets that are not weather-resistant can limit the success of a hunting trip to a great extent. This is especially true if your IR illuminator is not waterproof. Any place that is wet or humid would deem the illuminator unusable.

Similarly, you won’t be able to use it in rain or snow either. Therefore, weather resistance is a very important consideration. 

Usually, O-ring sealing is used to incur some level of moisture resistance in IR illuminators; however, they alone cannot make the gadget fully water-resistant.

IP67 weather resistance is a great option in this regard. Products that hold the IP67 rating can be used in rain, heat, humidity, and snow alike. Although, the higher the IP rating, the better.

Power Source

digital night vision monocular reviews

The power source may seem like a trivial feature, but it is not. It determines the number of hours for which you would be able to use your illuminator; hence, it directly affects the sport. IR illuminators come in both rechargeable and disposable battery options.

Rechargeable illuminators will run out of battery after a few hours, but you can recharge them. They are more efficient if the hunter is not going to spend all the time in the wilderness and will have access to a power source for charging. Rechargeable batteries cannot be used for extended periods of time continuously either.

Illuminators with disposable batteries are more widely used when hunters plan on a multiple-day camping trip on the hunting grounds. Under such circumstances, they do not have access to a power source.

Therefore, disposable batteries work best for them as they can be used for several hours continuously before they die out. However, users need to carry multiple packs of batteries which takes up space. They also have to buy batteries every now and then, which might become inconvenient.

Infrared Wavelength

The infrared wavelength of the beam emitted from the illuminator is another very important consideration. There are two popularly used wavelengths, 850nm, and 940nm. There isn’t much difference in the working of the two wavelengths.

However, there are other differences associated between the two. An 850nm illuminator has a better illumination range, and it is more efficient than the 940nm. However, it also produces a red glow when directly looked at the illuminator. 

Even though the IR beam is invisible to humans and the game you want to hunt, the red glow on the illuminator is noticeable when directly looked at. This glow could alert the animal, and the hunter might miss the opportunity.

940nm illuminators produce no glow. Therefore, they are completely invisible to the naked eye. However, they are 30-40% less efficient than 850nm illuminators and require more sensitive scopes for detection.

So, if you don’t mind the red glow from the illuminator and can’t compromise on the illuminator's range and efficiency, then 850nm illuminators are better for you. However, in cases where small-range surveillance and viewing are involved, the red glow could be a problem. Under such circumstances, a 940nm illuminator would perform very well.

Durability

An IR illuminator is as useful as it is durable. A model that lacks structural integrity and performance is no good. Therefore, it is very important to make sure that the layout of the illuminator is capable of withstanding operational abuse and the occasional bumps and falls encountered during use.

A popular and good choice of construction material is aluminum alloy. Various brands use different types of aluminum alloys because they are corrosion-resistant and are also quite sturdy.

Furthermore, the LEDs used within the illuminator should be durable as well. They must not die out or flicker in the middle of the operation. In this regard, buy illuminators that support LED bulbs with a lifespan of around 10,000 hours on average.


Types of IR Illuminators for Night Vision

IR illuminators for night vision are of three types and they differ on the basis of illumination range and price. They are lasers, diodes, and lamps.

Diodes are the least expensive and very easy to maintain. You can use them for short-range illumination. The illumination that they provide is not powerful enough to distinguish minor details.

Lamps are used for medium-range illumination. Through their illumination, users can see details like facial recognition. Lamps require maintenance and care for optimal performance. They are more expensive than diodes but less expensive than lasers.

Lasers are used for long-range illumination. They are sharp and powerful, which is why they can travel longer distances and illuminate more details. The long-range image clarity is excellent even during harsh weather conditions like rain and snow. Lasers are the most expensive type of IR illuminators.


Limitations of the Night Vision Over Thermal Optics

Both night vision and thermal optics are used for viewing fields and areas in low light conditions. While night visions make use of ambient or IR light for the purpose, thermal optics use heat signatures from the objects to paint a view.

Both types of optics are used for the same essential purpose but are quite different from each other in the working principle. 

To know the difference between the two, we must first understand how night vision works. Night vision optics work by using reflected light to detect contrast in the image.

Where the contrast is sharp (such as in areas with a white object over a black background), the image is clear, but in areas with lower contrast (such as in areas with a dark object against a black background), the difference is not detected.

Low contrast areas are not well-represented by night vision optics. Some night vision optics like scopes, monocular, or binoculars come integrated with IR illuminators, while many do not have an integrated or built-in illuminator. Night vision optics that lack an integrated illuminator often make use of IR illuminators and lasers sold separately.

However, in thermal optics, reflected light is not used. Rather, heat signatures emitted from different objects are used to form an image.

Thermal optics are very sensitive and can detect small heat changes in the surrounding. These signatures are represented in different color shades over the viewfinder of the optics.

Therefore, in thermal optics, no matter how low the contrast, the detection is much better than in night vision optics. Moreover, thermal optics do not need additional gadgets like illuminators to work with. 


FAQs

Are Night Visions Capable of Detecting IR?

best ir illuminator for night vision

Yes, night visions are capable of detecting Infrared light. Unlike the human eye, night vision optics are more sensitive to certain wavelengths that a naked eye cannot perceive. Infrared also has wavelengths that a naked human eye cannot see but are detectable by night vision optics.

Do the LEDs in IR illuminators glow?

Yes, IR LEDs in an illuminator glow. This is how they emit light to the surrounding. However, the wavelength of this glow is unperceivable by the human eye, making the glow invisible to us. However, in 850nm IR LEDs, you can see a faint glow at the lens of the illuminator if you are close to it.

Does night vision see through a glass surface?

A night vision optic can see through the glass. This means that using night vision optics, it is possible to see through a glass window. However, there has to be some ambient light present, or you should pair the night vision with an IR illuminator. In complete darkness, the night vision will not work.

How to know if the IR illuminator is working if we cannot see the wavelength with the naked eye?

IR illuminators often produce a faint red glow on the lens surface when they are turned on. You can detect this glow if you are standing close to the illuminator and looking directly at the lens. This method is widely used to test if the illuminator is working.

How are night vision and infrared scopes different?

Infrared scopes are more commonly known as thermal scopes. They detect infrared heat signatures from various objects to present an image of the field. Infrared scopes do not need ambient light and can work in complete darkness. However, they cannot work through glass. 

On the other hand, night vision scopes use ambient light, either visible or from an IR illuminator or laser, to visualize the surroundings. In the absence of light or complete darkness, a night vision scope does not work on its own. However, it can work through glass if a light is present.
