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.
Optical Surfaces produces ultra-smooth parabolic, ellipsoidal, spherical and toroidal mirrors for demanding applications.
Optical Surfaces manufactures high-quality custom prisms to customer-supplied specifications in quantities ranging from prototypes through batch runs to production quantities. These prisms are used in applications including image rotation, inversion, redirection and dispersing light into its constituent colours.
Optical Surfaces has produced a 12-page document entitled ‘Practical guide to surface quality’ — the second in a series of practical guides for optics users. The guide has been written to enable scientists and engineers to better understand an optics quoted surface quality as surface imperfections are typically the most misunderstood, misinterpreted and ambiguous of all optical specifications.
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.
