A: Traditional Night Vision, also known as Image Intensification Technology or I2, has been around for a long time and has progressed over several generations. The basic process is a special device inside of an optic, called an image intensifier tube, gathers ambient light through the lens of the optic and passes it through other electronics within the device onto a screen within the eyepiece. There’s obviously more to it than that but that’s basically the process. Night vision comes in several generations, but most commonly today we use some variations of Generation 3. Generally speaking, the higher the generation and higher the specs the better the image through the unit will look. Night vision is commonly presented to the user in either a green or white image.

Q: Is Night Vision / Thermal Legal?
A: Yes, here in the United States, U.S. Persons (Citizens, or Permanent U.S. Residents) may own and use Night Vision and Thermal Optics. However, it is against the law to take these devices out of the country, unless specifically approved by the U.S. State Department with proper licensing. Night Vision and Thermal devices fall under the International Traffic in Arms Regulations, or ITAR for short. Q: Is Night Vision / Thermal Legal?
Generally speaking, if it is a civilian night vision device, there is no problem at all.
Q: What is Thermal Imaging and how does it differ from Night Vision?
A: Thermal hasn’t been around for as long NV but over the last few years has seen a tremendous increase in the performance and in the amount of users. To keep this in fairly basic terms, thermal sees heat, and night vision sees amplified light. A thermal imaging unit uses a special lens, usually made from germanium, which focuses infrared energy onto a detector. The detector then passes the information it collects through other electronics and ultimately onto a screen. The user sees an image based on temperature variations within the field of view. Most thermals allow the user to control many aspects of the image including color pallet, contrast, digital zoom, etc.
Our factory also produces multi-functional thermal vision products, like MH-6100B/MH-675/MH-350B thermal vision binoculars, MH-N thermal car camera and so on.
Q: What about IR Illuminators?
A: An IR illuminator is an invisible "flashlight" for lack of a better term. When using a night vision device in an extremely dark environment, there may not be enough ambient light to allow the unit to perform adequately. An IR illuminator will produce a beam that can only be seen through night vision and not by the naked eye. Many night vision devices have an illuminator built in but most users prefer a more powerful, stand-alone illuminator to accompany their devices. This is particular crucial with gen 1 and 2 devices. Many IR lasers also incorporate a built in IR illuminator.
