Overview
The Lambert Intensifier II18 is a low light level camera attachment designed to enhance the sensitivity of standard monochrome video cameras with 1/2 or 2/3-inch image sensors. It allows for image detection at light levels as low as 10^-5 lux using an f/1.4 lens. The device is equipped with a Generation II Image Intensifier, providing bright, high-definition images across various light levels through adjustable gain control.
