Beam Expander and Beam Compressor for Optino

SpotOptics can provide Beam Expanders that can expand(/compress) the optical beam to test optical elements up to 120mm diameter.

Beam Expander BE120 mounted on the Dual Channel wavefront sensor Optino600.

The same unit can be also used in Beam Compressor configuration.

Beam Expander contains optical elements whose effect/aberrations should be subtracted with the calibration. We provide the setup for calibration with our Beam Expanders.
