Optical Surfaces Ltd has been producing optical components and systems for the last 50 years and is now accepted as one of the world’s leading manufacturers of high precision optics.
The company’s ISO 9001-2008 approved manufacturing workshops and test facilities are deep underground in a series of tunnels excavated in solid chalk. This provides an environment where temperature is naturally stable and vibration is extremely low. With such stable conditions testing, particularly with long path lengths, becomes quantifiable and reliable.
In addition to these natural advantages, Optical Surfaces has invested in an extensive range of test equipment and have developed methods to ensure accurate and reliable testing.
- Optical Surfaces test facilities currently include:
- Several ZYGO GPI interferometers
- 500 mm Fizeau – interfaced with ZYGO Flash Phase software
- Phase shifting – Laser Unequal Path Interferometers (LUPI)
- Class 10,000 (Class 7) clean room
Wherever possible all test equipment is traceable to National Standards.
Optical Surfaces also has access to surface roughness testing and other high accuracy metrology.
Test reports include details of mechanical, optical and environmental data.
Optical Surfaces are committed to enhancing our test capabilities and are constantly reviewing the facilities in light of technological advances.
