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 is offering high-precision toroidal mirrors (toroids) that can be made to customers’ exact specifications. Toroidal mirrors are widely used for correction of aberration in a range of applications served by spectroscopic instruments, monochromators and imaging devices that require pinpoint focusing.
Optical Surfaces has introduced small-diameter (25–60mm) reflective beam expanders, which are suitable for space-restricted applications such as high-power lasers and multi-wavelength interferometry. Incorporating high-precision off-axis mirrors, the reflective beam expanders are said to provide an unobstructed output and highly efficient transmission.
Optical Surfaces has been selected by a spectrophotometer manufacturer to supply ultra-high-precision matched beamsplitter/compensator optics for the interferometer that lies at the heart of its high-resolution FTIR system.
Optical Surfaces has introduced the OS-Z range of mirror mounts, developed to support off-axis paraboloid, spherical and flat mirrors in a way that overcomes a number of constraints imposed by general-purpose mounts.
Off-axis paraboloids (OAPs) direct and focus incident collimated light at a specific angle, allowing unrestricted access to the focal point as well as reducing the size and minimising the weight of an optical design. Working with high-quality optical glasses, Optical Surfaces produces standard OAPs from 60mm to 600mm in diameter.
