Concave & Convex Spherical Mirrors from Optical Surfaces Ltd

Optical Surfaces Ltd. is a leading international supplier of concave and convex spherical mirrors made to your exact specification.

A spherical mirror is a mirror which has the shape of a piece cut out of a spherical surface. Spherical mirrors of various radii and diameters have been supplied by Optical Surfaces to organisations worldwide for over 50 years. High precision spherical mirrors produced by Optical Surfaces have been used in a huge variety of applications including Schlieren imaging, Wind tunnels, Observatory spectrographs, Bubble chambers and, as Hindle spheres, to test hyperboloids.

A 1.3-metre diameter spectrograph spherical mirror was supplied to the Royal Greenwich Observatory and was installed on the 2.5-metre Isaac Newton Telescope located at La Palma on the Canary Islands. The spectrograph contributed to obtaining the first observable evidence of the existence of black holes.

With 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. These same unique production facilities allow Optical Surfaces to manufacture and test very long radii spheres by taking full advantage of the long tunnels we have at our disposal.

Optical Surfaces ISO 9001-2000 approved manufacturing facility provides the flexible resources to supply from single specialist requirements to OEM quantities.  Benefiting from its stable environment, quality testing becomes quantifiable and reliable. All spherical mirrors are provided with a complete quality test assurance report.
