A thermal imaging unit uses a special lens, usually made from germanium, which focuses infrared energy onto a detector. To keep this in fairly basic terms, thermal sees heat, and night vision sees amplified light. Q: What is Thermal Imaging and how does it differ from Night Vision?Ī: 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. If you would like to discuss in more technical detail please let us know. Night vision is commonly presented to the user in either a green or white image.
Generally speaking, the higher the generation and higher the specs (more on that later) the better the image through the unit will look. Night vision comes in several generations, but most commonly today we use some variations of Generation 3. There’s obviously more to it than that but that’s basically the process. 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. If you have questions on any of this information, we will be happy to discuss and clarify.Ī: Traditional Night Vision, also known as Image Intensification Technology or I2, has been around for a long time and has progressed over several generations. To make a long story short, the goal here is we don’t want these powerful devices to fall into the hands of our enemies.
Night Vision and Thermal devices fall under the International Traffic in Arms Regulations, or ITAR for short.
It is also against the law to allow a non-U.S. However, it is against the law to take these devices out of the country for any reason. A: Yes, here in the United States, citizens may own and use Night Vision and Thermal Optics.
