To wrap this guide up, let’s talk a little bit more about IR illuminators. They were discussed earlier but you deserve a straight up answer as to why they are necessary for these types of devices. The primary reason is that they significantly increase the vision in extremely low-light conditions. Your night vision goggles will be able to see infrared light with this technology and your sight will be enhanced because of it.
Of course, at the end of the day, night vision devices are dependent on magnification, contrast, ambient light, and atmospheric transparency. Thus, the addition of an IR illuminator will enhance your detection ranges and image sharpness.
