Night-vision devices were introduced in the German Army as early as 1939 [citation needed] and were used in World War II. AEG started developing its first devices in 1935. In mid-1943, the German Army began testing infrared night-vision devices and telescopic rangefinders mounted on Panther tanks. Two arrangements were constructed.
The AN/PSQ-42 Enhanced Night Vision Goggle-Binocular (ENVG-B) is a third-generation passive binocular night vision device developed for the United States Army by L3Harris. It combines dual tube image-intensifying (I²) and thermal-imaging technologies into a single goggle, enabling vision in low-light conditions.
The AN/PVS-7 is a single tube biocular night vision device. Third-generation image intensifiers are able to be installed and are standard for military night vision. Most newer PVS-7 intensifier tubes are auto-gated to prevent image intensifier damage if exposed to intense light. The goggles have a built-in infrared Illuminator for low-light ...

Active infrared night-vision combines infrared illumination of spectral range 700–1,000 nm (just over the visible spectrum of the human eye) with CCD cameras sensitive to this light. The resulting scene, which is apparently dark to a human observer, appears as a monochrome image on a normal display device. [ 13 ]
An example of a noted shortcoming ultimately considered insignificant was an enemies ability to detect the reflection of the AN/PVS-4 objective lens using an active infrared night vision device. The IR device needed to detect the AN/PVS-4 required a straight-on unobstructed view, and AN/PVS-4 detection only occurred using an active device (as ...
