Ultra flat etalons improve precision of Fabry–Pérot interferometers

Ultra flat etalons improve precision of Fabry–Pérot interferometers

Product News Monday, August 7, 2023: Optical Surfaces Ltd.

Benefiting from a uniquely stable production environment – Optical Surfaces Ltd is recognised as one of the world's finest manufacturers of solid and air spaced etalons.
 
Etalons are widely used in telecommunications, lasers, and spectroscopy to control and measure the wavelengths of light. Recent advances in fabrication techniques, developed by Optical Surfaces Ltd, has enabled the creation of a new generation of very precise tuneable Fabry–Pérot interferometers.   Dr Aris Kouris, sales director said “Working deep inside a chalk cliff, where temperature variation is negligible all year around, our skilled optical craftsmen can routinely create etalon pairs with ultra-low microroughness and surface accuracies that are better than lambda/300 peak to valley. As a result, we are the preferred supplier of matched etalon pairs to a growing group of discerning customers including a leading manufacturer of ultra-high resolution tuneable Fabry Perot interferometers”.   He added “Available in a range of shapes our etalons are designed for use at customer-defined wavelengths within the range 190 nanometres to about 2 microns. They are supplied with wedge angles of 5 minutes of arc for smaller diameters, rising in steps to a wedge angle of 40 minutes of arc for diameters from 70 - 170mm. Optical Surfaces etalons are available as standard in materials including UV grade Silica, Silicon and Germanium".   For further information on ultra-high precision etalons for use in applications in interferometry, lasers and high-resolution spectroscopy please visit www.optisurf.com/index.php/products/etalons/ or contact Optical Surfaces Ltd. on +44-208-668-6126 / sales@optisurf.com.   Optical Surfaces Ltd. has been producing optical components and systems for leading academic and industrial research groups for more than 50 years. The company’s ISO 9001-2015 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.   ----------- Worldwide HQ Optical Surfaces Ltd.
