High Precision Spherical Mirrors

High precision spherical mirrors produced by Optical Surfaces Ltd. are used in a huge variety of applications including Schlieren imaging, wind tunnels, observatory spectrographs, bubble chambers and to test hyperboloids (as Hindle spheres).

Benefiting from workshops and test facilities deep underground, where temperatures remain constant and vibration is practically non-existent, Optical Surfaces routinely produces high precision spherical mirrors in a wide range of materials and coatings. Typical achievable surface accuracy is better than lambda/30 p-v, surface quality 10:5 scratch dig and micro roughness less than 1.2nm RMS.

A typical example of these capabilities is a 1.3-metre diameter spectrograph spherical mirror supplied to the Royal Greenwich Observatory (UK) that was installed on the 2.5-metre Isaac Newton Telescope located at La Palma in the Canary Islands. This spectrograph contributed to obtaining the first observable evidence of the existence of black holes.

Optical Surfaces Ltd has been producing optical components, mounted 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 for space and ground based telescope applications. 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.
