Optical Surfaces Ltd. has launched a handbook to enable users to get top performance from their optics.
The company offers standard OAPs from 60mm to 600mm diameter to direct and focus incident collimated light at a specific angle, allowing unrestricted access to the focal point.
Unlike standard parabolic mirrors, Off-Axis Paraboloids reduce the size and minimise the weight of an optical design.
Optical Surfaces Ltd. works with high quality optical glass in a stable manufacturing environment and a highly skilled team of engineers and craftsmen to routinely produce OAPs with surface accuracy to lambda/20 (peak-to-valley) depending upon off-axis angles.
Proprietary polishing techniques are employed to, depending on the surface accuracy required, achieve the natural limit to the off-axis angle of around 25-30 degrees and surface micro-roughness of less than 1 nm.
A range of coatings is available for standard and custom components from metallic with or without protective overcoat to multilayer dielectrics and ultra hard coatings.
Standard and custom design Off-axis Parabolic Mirrors from Optical Surfaces have been chosen by many leading establishments around the world for undertaking applications including Schleiren, FLIR and MTF testing, high power laser focusing, focusing upon astronomical objects, collimating reference wavefronts, beam expansion and bore sight alignment for missile guidance systems.
