Optical Surfaces Ltd

Optical Surfaces Ltd, has been producing optical components and systems for more than 30 years and is now accepted as one of Europe's leading manufacturers of high-precision optics.

The main 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 become 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.

Interferometers routinely used include Zygo, Twyman Green, Scatterplate, Fizeau up to 600mm dia. Laser unequal path (LUPI) and point diffraction. They are able to test surface geometry, interfacing with our Wyko computer fringe analysis to confirm final wavefront.
