US NightVision SNS-1 Night Vision Monocular
- 3rd Generation
The SNS-1 features an ITT Generation 3 image tube. These tubes will have a few dark spots in the image area, but they do not affect the performance of the imaging system. The SNS-1 is a great value in a 3rd generation night vision monocular instrument.
There are many variables that affect the distance that one can see with a night vision device; the object's size, ambient weather and lighting conditions, the level of detail needed for recognition, etc. The important factors to consider when evaluating any night vision device are the generation of the intensifier tube along with its specified resolution and s/n ratio. The magnification, clarity, and light transmission performance of the NVD's optics also contribute to its low/no-light performance capabilities.
All NVDs sold by B&H feature bright-light protection systems. However, this does not mean that bright light can/will not damage the device. Exposure to bright light compromises the longevity and performance of image intensifier tubes.
