Electro Optical Components offers Objective Lens and Beam Shapers & Beam Expanders for Lasers.
Objective Lens is an optimized optical system, with the flat and chromatic aberration free image over the entire field of view, with coating covers 532-1100nm.
Beam Shapers are designed to change the Gaussian profile of a light source to a Top-Hat profile. The output beam is collimated. This allows it to be used with normal lenses after the beam shaper.
Common Beam Expanders are Galilean type which have one negative input lens and one positive output lens. The beam expansion ratio for a Gaussian beam depends not only on the specifications of the beam expander, but also on the laser beam parameters as well as the positions of the optical lenses.
These objective lens, beam shapers and beam expanders are sold in North America by:
