PARABOLOID FOCUS

Off-Axis Parabolic Mirrors (Paraboloids)

Off-Axis Parabolic Mirrors (Paraboloids)Unlike standard parabolic mirrors, Off-Axis Paraboloids (OAP) direct and focus incident collimated light at a specific angle, allowing unrestricted access to the focal point as well as reducing the size and minimising the weight of an optical design.

Variable Focus Motorised Beam Expanders

Optical Surfaces Ltd. is a leading supplier of variable focus motorised beam expanders for LIDAR systems used in meteorological applications. An off-axis reflective beam expander greatly reduces the blind zone of LIDAR systems and therefore often offers the best solution to this problem. In LIDAR systems, such as Doppler Wind LIDAR, the wavefront performance of the beam expander is very important for the LIDAR efficiency. Variable focus motorised beam expanders from Optical ...
