PARABOLOID FOCUS

Off-Axis Parabolic Mirrors (Paraboloids)

Off-Axis Parabolic Mirrors (Paraboloids)Unlike standard parabolic mirrors, Off-Axis Paraboloids (OAP) 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.

Fizeau Interferometer for Testing Very Large Diameter Flats

Fizeau Interferometer for Testing Very Large Diameter Flats

Optical Surfaces Ltd has developed a 600mm Fizeau interferometer enabling it to now offer quality testing of flats in a single aperture up to 600mm in diameter. This is a capability that only a few optical testing and manufacturing centres around the world possess. Housed in an ultra-stable testing environment, this interferometric set-up will allow direct qualification of larger flat mirrors up to 600mm diameter by testing them directly over their ...

Beam Compressor for Magdalena Ridge Observatory Interferometer

Beam Compressor for Magdalena Ridge Observatory Interferometer

Optical Surfaces Ltd. has been selected by the Magdalena Ridge Observatory (Socorro, New Mexico, USA) to produce an ultra-stable 7.5x off-axis beam compressor that will form a key beam transfer element in the facility's optical interferometer. When completed the Magdalena Ridge Observatory Interferometer (MROI) will be one of the world's most powerful optical-infrared interferometers, dedicated to high resolution imaging of all types of astronomical objects. The objects that will be observed ...
