Off-axis parabolic mirrors can be a useful tool in optical design. OAPs combine the achromatic and diffraction limited imaging properties of a parabolic mirror with the ability to deviate the light path off-axis, which is useful for most imaging systems. OAP’s offer the ability to focus collimated light without introducing spherical aberration. Continue…
Optical Surfaces Limited are a UK based company supplying the world with optical components and instruments. We specialise in large optics, beam expanders, collimators and prototypes, plus custom systems and optics.
Over the last 50 years – Optical Surfaces Ltd has established itself as a leading international manufacturer of top quality, high precision optical components and systems. We have contributed to many major projects worldwide involved in areas such as:
• fundamental physics • astronomy • space • defence and the environment
Optical Surfaces Ltd. reports how its high precision reference flat mirrors are enabling testing and precise alignment of Earth observation satellite telescopes.
Today, satellite images play a major role in gathering information about the Earth's ecosphere. This data, obtained by satellite-based optical telescopes provides valuable information about geological features, urban development, weather phenomena, and increasingly reliable prediction of crop yields, which are being impacted by the effects of climate change.
To obtain ...
Benefiting from a uniquely stable manufacturing environment - Optical Surfaces Ltd. can routinely produce challenging prototype and custom optics to the highest levels of precision possible.
The company's ISO 9001-2015 approved manufacturing workshops and test facilities are deep underground in an area excavated from solid chalk. This provides an environment where the temperature is naturally constant, and vibration is extremely low. These are important considerations when making, mounting, and testing high ...
Optical Surfaces Ltd has been selected by the Gérard Mourou Center for Ultrafast Optical Science (CUOS) at the University of Michigan (USA) to provide beam expander optics for its ground-breaking Zettawatt-Equivalent Ultrashort pulse laser System (ZEUS).Sponsored by the U.S. National Science Foundation, the ZEUS laser facility is being constructed to allow a Petawatt laser pulse from one of its beamlines to collide with a beam of GeV-energy electrons generated by ...
Optical Surfaces Ltd is an established manufacturer and supplier of large-area windows of optical quality for military sensing applications.
Optical windows are a critical component in a variety of defence applications including aerial surveillance, reconnaissance and targeting. For over 50 years – Optical Surfaces Ltd has been working with materials including fused silica, BK-7 and Germanium to produce defence grade windows up to 600mm in diameter.
Typically, large diameter optical windows for ...
Optical Surfaces Ltd. is a leading supplier of off-axis parabolic and flat mirrors, the key optical elements in Infrared (IR) collimators commonly used for evaluating the performance of thermal imaging systems.
The function of an IR collimator is to generate a thermal image closely resembling the thermal scene at a test plate. Performance tests often performed on Thermal Imaging systems include measurement of the Minimum Resolvable Temperature Difference (MRTD) and the ...
