what is the difference between thermal devices and night vision?

Thermal vs. Night Vision

Postby ATN_Rep on Tue Jul 29, 2008 2:03 pm

Thank you for your inquiry; their is actually a very large difference between Thermal Viewers and Night Vision. Thermal works on the principal of heat signature translation. Night vision works on the principal of amplifying ambient light. With Thermal an image typically looks like and old fashioned camera negative. With Night Vision, the image looks greenish because of the phosphorus screen that the electrons hit after amplification to recreate the image. Thermal has a longer operating distance and can be used both day and night. Night Vision tops off with Gen 3 at about 300 yards or so, also depending on environmental conditions. Night vision will give you more recognizable detail vs. Thermal, but thermal can see through brush and through fog.

I hope this clears up the two technologies.
