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...

Optical Surfaces Ltd is an established supplier of Ritchey-Chrétien (RC) telescope optics for high precision surveillance applications. Typically incorporating primary and secondary hyperbolic mirrors – RC designs offer compactness, a good field of view and are free of optical errors and spherical aberrations inherent with traditional reflecting telescope optics. Benefitting from a simple two mirror design - RC telescope optics provide exceptional image quality, high thermal stability and...

Drawing upon its uniquely stable production facility - Optical Surfaces Ltd. has established itself as a leading supplier of larger diameter hyperbolic mirrors and the extremely tight tolerances and accuracy that these optics demand. Hyperbolic mirrors are used in telescopes to correct aberrations in Ritchey-Chrétien designs, such as the Hubble telescope, by focusing off-axis light, allowing for wider fields of view and high optical performance. They are also often used as secondary mirrors in...

Optical Surfaces Ltd has received an order from Armstrong Optical, a leading UK supplier of optical metrology instruments, to supply high specification transmission and reference flats for a custom interferometer. Being built for a leading defence contractor the interferometer will be used to evaluate the quality and certify the performance of advanced military optical systems. Darren Wiles, R&D Manager at Armstrong Optical commented “Reference flat interferometry is a trusted optical...
