Off-axis paraboloids, sometimes referred to off-axis parabolic mirrors or off-axis parabola, provide optical designers with an unobstructed aperture allowing complete access to the focal region as well as reducing the size and minimising the weight of a design.They are especially suitable for broadband or multiple wavelength applications due to their completely achromatic performance. All together these advantages produce a cost-effective solution for many optical design problems with no compromise in performance.
Production approved to ISO 9001-2008 the quality of OAPs from Optical Surfaces Ltd. is ensured using a range of interferometric and surface test measurements on all optics leaving the factory. The company offers a wide range of coatings to enable optimised OAP performance in applications including Beam Collimation / Expansion, FLIR testing, High power laser beam focusing, Astronomical spectrographs,Target projection, MTF referencing and MRTD testing.
Benefiting from a uniquely stable manufacturing environment, and over 50 years’ experience and expertise, Optical Surfaces OAPs are used by many leading research establishments and companies around the world
