Off-axis parabolic mirrors for optical instruments

15th May 2020

Off-axis parabolic mirrors are the most common type of aspherical mirrors used in optical instruments because they are free from spherical aberrations, and can focus a parallel beam to a point or point source to infinity.

Employing off-axis parabolic mirrors in an instrument design allows optical engineers to not only minimise the size and weight of their system but also allows more interactive space around the focal point without disrupting the beam thereby increasing efficiency. OAP mirrors are especially suitable for broadband or multiple wavelength applications.

Benefiting from a stable manufacturing environment and employing proprietary production techniques, Optical Surfaces highly experienced and skilled engineering team are world renowned for producing off-axis parabolic mirrors with unmatched surface accuracy, surface quality and surface slope errors.

Working to strict ISO 9001-2015 guidelines all off-axis parabolic mirrors manufactured by Optical Surfaces are supplied with test data including high accuracy metrology, surface roughness and environmental data.
