[SatNews] The new Model 305 Fixed Focus Non-Browning Lens from Resolve Optics Ltd. has been designed to provide uncompromised performance with large image format cameras and sensors used in environments subject to radiation.

Measuring only 30mm in diameter, the compact f2 lens delivers high image resolution and minimum geometric distortion from 400 - 750 nm. Manufactured to the highest quality standards from cerium doped glass or synthetic silica, the Model 305 lens is able to withstand radiation exposure of up to 53 kGy (108 rads) and temperatures up to 55 degrees centigrade without discoloration. Designed to give a 40° field of view in both the vertical and horizontal planes and 25 Cycles/mm, the Model 305 lens is able to provide uncompromised optical performance for images up to 18mm in diameter. Available with manual or motorized iris, the Model 305 provides a focus from 35 mm in front of the lens to infinity. Because of the requirement in nuclear vision and space research applications for cameras to be radiation-hard and to cover a large image format, no standard lens have been available to meet these dual demands until this introduction of the Model 305.
