GRIN cylindrical lenses
Gradient-index (GRIN) cylindrical lenses are designed to collimate the slow axis of laser diodes and bars. The slow-axis line of lenses features an aberration-free 0.25 numerical aperture with a 2.6-mm focal length and 2.56-mm working distance. The long working distance allows insertion of fast-axis-collimating lenses.
