Optical Surfaces Ltd.,
a leading manufacturer of high precision optics, has over 40 years experience
of supplying the world's leading laboratories with high performance parabolic
Parabolic mirrors offer excellent correction of spherical aberration. Parabolic
mirrors can either be on-axis or off-axis. On-axis parabolic mirrors produce
collimated reflected light and are used in applications that require very fast
focusing and high energy densities. Off-axis parabolic mirrors 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. Typical applications for off-axis parabolic mirrors include high
power laser focusing, focusing upon distant 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 are able to produce on- and off-axis parabolic mirrors up to 800 mm
in diameter with surface accuracy's to lambda/20 p-v and surface micro-roughness
of ~ 1 nm rms dependant on diameter and f number. Benefiting from a stabilised
manufacturing environment Optical Surfaces Ltd can, depending on the surface
accuracy required, generate very fast focusing mirrors to f 0.5 using proprietary
production techniques. 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.
Production approved to ISO 9001-2000 the high quality of parabolic mirrors
from Optical Surfaces Ltd. is ensured by a range of interferometric and surface
test measurements on all optics and optical systems leaving the factory.
