Optical Surfaces Ltd. has established a worldwide reputation of being able to deal with the extremely tight tolerances and accuracy that hyperbolic optics demand.

Hyperboloids are generally used in optical telescope systems where good off-axis performance is an important requirement. Optical Surfaces supplied hyperboloids have been at the heart of many deep space and earth observation satellites including BNSC's Top Sat, the NASA swift explorer as well as ESA's XMM and NigeriaSAT-2.

Benefiting from a uniquely stable manufacturing environment and proprietary production techniques - Optical Surfaces Ltd.'s skilled craftsmen are able to economically produce hyperbolic optics up to 500mm diameter with typical wavefront error of lambda/20 P-V, surface finish of 10/5 and microroughness less than 1.2nm RMS.

Hyperbolic optics can be supplied mounted or mounted and with a coating exactly optimised for your application. Where weight is an issue - Optical Surfaces also has experience in producing hyperboloids with light-weighting options.

Optical Surfaces Ltd has been producing optical components and systems for more than 50 years and is now accepted as one of the world's leading manufacturers of high-precision optics and optical systems.

The company's ISO 9001-2008 approved manufacturing workshops and test facilities are deep underground in a series of tunnels excavated in solid chalk where temperature remains constant and vibration is practically non-existent.

With such stable conditions testing, particularly with long path lengths, becomes quantifiable and reliable.

Working with these natural advantages is a highly skilled team of craftsmen with a commitment to excellence in both product quality and customer service.
