SMARTNOBLE'S Spherical Third-generation Night Vision Image Intensifier

Spherical Third-generation Night Vision Image Intensifier

Features: Inverted Image Output, Spherical Output Surface

This type of third-generation low-light image intensifier adopts a light-shielding glass with anti-halo blackening as the input window and a fiber optic inverter as the output window. The output surface is SR40mm concave spherical, and the output image is inverted by 180° compared to the input image.
