Rather than having to determine the correct focusing distance and setting the lens to that focal point, a fixed-focus lens relies on sufficient depth of field to produce sharp images. The 6mm focal length Model 214 non browning lens delivers high image resolution (f2) and minimal geometric distortion from 400-750nm. Manufactured to the highest standards, from cerium doped glass, the Model 214 is able to withstand radiation exposure of up to 100,000,000 rads and temperatures up to 55°C without discoloration.
