The Slow-Axis-Collimation lens is a highly efficient means of forming the beam in the slow axis of diode lasers. It is available as a single lens. All of our optics are produced using high-quality optical glass. The exacting product tolerances guarantee efficient collimation of the light from all emitters and compatibility with laser bars and stacks.
