Proprietary technique produces ultra smooth laser mirrors
Optical Surfaces Ltd. has pioneered a pitch-polishing technique, that produces consistently low surface microroughness on off-axis parabolic mirrors used as key focusing elements for high power laser experiments. Microroughness is a component of surface texture, it...
High precision dichroic beamsplitters for astronomical research
Dichroic beamsplitters from Optical Surfaces Ltd are commonly used as light guiding optics in telescope spectrographs and to enable multichannel CCD cameras to simultaneously acquire images in different colours. Beamsplitters operate by dividing an incident beam of...
Improving telescope vision with artificial guide stars
Optical Surfaces Ltd report supply of fourteen 100mm diameter field selector mirrors and a 400mm diameter reference flat to TNO (Delft, Netherlands) for a Laser Launch System designed to improve telescope vision with artificial guide stars. Designed and built by ESO...
Aspheric lenses for high power laser research
Optical Surfaces Ltd is a leading producer of large diameter aspheric lenses used as critical focusing optics in high-power laser research. Aspheric lenses provide a cost-effective way of reducing the number of optical elements in a focusing system thereby making them...
Extremely large reference flat for testing space optics
Optical Surfaces Ltd. has received an order from JEEWOO Photonics Ltd (Daejeon, South Korea) to produce a 700mm diameter reference flat – a key component in an optical test system being developed for a space optics organisation. The optical test system is...
Low profile mount offers stable platform for large mirrors
Optical Surfaces Ltd. has developed a new low profile mirror mount that provides a secure platform for large and heavy high-precision flat, spherical, on-axis and off-axis mirrors. Robustly designed in black anodized aluminium, the mount can be tailored to match the...
High stability beam collimators for military optics testing
Optical Surfaces Ltd has supplied two reflective beam collimators to a leading European supplier of high precision optics to military and defence contractors. Reflective beam collimators are mirror assemblies that take divergent or convergent incoming light and...
