The Challenger GS 3.5×50 night vision Device

Night vision monocular Challenger GS 3.5×50, produced under the brand Pulsar, made in durable, lightweight, ergonomic dust – and waterproof housing made of metal and plastic.

A specially designed five-element eyepiece enhances the sharpness and contrast of the image. Comfortable soft rubber Eyecup conceals the luminescence of the TUBE and allows the observer to remain unnoticed. All operations with the device are performed with a single switch that sequentially activates the device and the built-in powerful IR illumination for observation at a distance above average. Two diametrically opposed mounting sockets make it possible to fix on the instrument with additional IR illumination and set it on a tripod.

The combination of the progressive optical scheme of the R-Contact and the specially designed Novosibirsk instrument-making plant image intensifier TUBE CF-Super (Gen. 1+) with fiber washer ensures the almost complete lack of distortion at the edge of the field of view, sharpness and geometric accuracy even in the peripheral areas of the TUBE’s screen and a high gain of light.

Due to the special spherical shape of the photocathode image intensifier devices have a high and uniform resolution across the surface of the screen, not from less than 42 strokes/mm in the center to not less than 24 strokes/mm on the edge, with an average resolution across the field of view of about 36 lines per mm.
