Optical Surfaces has announced a new technical datasheet describing its
range of standard and customer specified off axis paraboloids. Off-axis
paraboloids (OAPs) provide 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. Benefiting from
over 50 years experience in producing the most demanding high precision
optics and optical systems - Optical Surfaces OAPs are used by many
leading research establishments and companies around the world.
Typical applications for off axis paraboloids include high power laser
focusing, focusing upon astronomical objects, collimating reference
wavefronts, beam expansion, MTF measurement, MRTD testing and bore
sight alignment for missile guidance systems.
Optical Surfaces Ltd's highly experienced and skilled team of engineers
and craftsmen can typically produce off-axis parabolic mirrors up to
600 mm in diameter with surface accuracy's to lambda/20 p-v depending
upon off-axis angles. With proprietary polishing techniques
Optical Surfaces can, depending on the surface accuracy required,
achieve the natural limit to the off-axis angle of around 25-30 degrees
and surface micro-roughness on aspherics of ~ 1 nm rms. 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.
