Optical Surfaces Ltd is a respected supplier of ultra-high precision optical etalons for use in telecommunication, laser, interferometric and spectroscopic applications. An optical etalon, also known as a Fabry–Pérot etalon, consists of two parallel reflecting surfaces with an air gap in between, or as a solid transparent plate. Optical etalons play a crucial role in controlling and manipulating light in various optical systems. The performance of an etalon may be limited by factors such as...

Optical Surfaces Ltd has developed a novel approach for delivering modular large beam collimators – a key component for assembly and testing of Free Space Optical (FSO) communication systems. FSO communication uses light to transmit data wirelessly through air or space. This cable-free data transmission methodology offers ultra-high bandwidth and enhanced security compared to traditional RF systems. The collimator in an FSO communication system serves as an alignment and testing tool ensuring...

Optical Surfaces Ltd. is a leading supplier of ultra-high precision optical flats to research establishments and national standards laboratories worldwide. Using highly stable optical materials such as Zerodur®, and benefiting from a thermally stable production environment, Optical Surfaces routinely achieves surface accuracies of better than ʎ/20 peak to valley and surface roughness of less than 10 A rms on optical flats up to 600mm in diameter. A 475mm diameter optical flat used as a...

Optical Surfaces Ltd offers custom off-axis parabolic mirrors with a wide variety of coating options optimised for the most demanding high-power laser, defence, aerospace, spectroscopy and astronomy applications. Off-axis parabolic mirrors (OAP’s) 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 or beam delivery systems. OAP’s offer the ability to focus collimated light...

Optical Surfaces Ltd is a leading supplier of larger diameter debris shields for high energy laser applications. Debris shields are used to prevent damage to critical high precision optical components in beam delivery systems caused by dust, shrapnel and fragments originating from the target in high energy laser experiments. Optical Surfaces debris shields offer a cost-effective solution that extend the operational life of expensive high power refractive and reflective optics. Placed in the...
