Etalons are suitable for telecommunications and laser applications
Optical Surfacescontact supplier
Optical Surfaces is offering Fabry-Perot etalons, which are used for measuring the wavelengths of light in telecommunications, lasers and spectroscopic applications.
The etalons are available in a range of sizes of up to 150mm in diameter with matching accuracies to λ/300.
They are available in air-spaced and solid forms and are designed for use a wavelengths between 190nm to about 2microns.
Those with smaller diameters are supplied with wedge angles of 5 min of arc, which rises in steps to a wedge angle of 40 min of arc for units with a diameter of greater than 70mm.
Optics from Optical Surfaces have helped Surrey Satellite Technology win the 2012 Sir Arthur Clarke award for ‘Best Space Activity — Industry/Project’ for the Nigeriasat-2 Earth observation satellite. Nigeriasat-2 was built for the Nigerian Space Agency (NASRDA).
Optical Surfaces is offering a range of fully enclosed pre-aligned reflective collimators for applications including MTF testing, optical resolution testing, star simulation, MRTD testing and bore-sight alignment and inspection.
Tube collimators from Optical Surfaces simplify the alignment of off-axis paraboloids. Applications include the resolution tests of optics, bore sighting for alignment and inspection of customer systems and star simulation.
This data sheet from Optical Surfaces is dedicated to on-axis paraboloids for applications in science, space and defence research.
Optical Surfaces has supplied a 350mm-diameter on-axis ellipsoidal mirror to the Kiepenheuer-Institut für Sonnenphysik (KIS) — an institute in Freiberg, Germany, that carries out solar research with ground-based telescopes.
