Suitable for use broadband or multiple-wavelength applications such as telescopes, beam expanders, forward-looking infrared test systems, collimators, spectrometers and laser beam focusing
Optical Surfaces, specialist in large high precision optics, says it has considerable experience of supplying off-axis paraboloids with diameters up to 600mm, surface accuracy of up to lambda/20 and off-axis angles up to 25deg.
Optical Surfaces has developed proprietary production tools to directly generate off-axis parabolic profiles, producing time savings in the long lead times often associated with such mirrors.
Skilled and experienced craftsmen then carry out the final figuring to ensure the highest quality and precision.
Off-axis paraboloids offer the advantage of an unobstructed aperture and access to the focal region to system designers.
They are especially suitable for broadband or multiple wavelength applications due to their completely achromatic performance.
Off-axis paraboloids can be the solution to many problems in optical design.
They can often provide the most cost-effective answer with no compromise in performance.
A range of coatings is available for standard and custom components from metallic with or without protective overcoat to multilayer dielectrics and ultra hard coatings for high-power lasers. Optical Surfaces off-axis paraboloids are suitable for use in broadband or multiple-wavelength applications such as telescopes, beam expanders, forward-looking infrared test systems, collimators, spectrometers and laser beam focusing.
