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.

Optical Surfaces Ltd has received an order to supply the University of Oxford, UK with 3 speciality glass prisms for a study that will enable defining key components in the state-of-the-art HARMONI spectrometer being developed for ESO's Extremely Large Telescope (ELT).
The ELT, a flagship project of the European Southern Observatory (ESO), will be the largest ground-based optical telescope ever built. Located in Chile, with a primary mirror of 39m diameter, ...
Optical Surfaces Ltd. is a specialist producer of extremely durable, high performance coated mirrors, up to 600 mm in diameter, for use with high power femtosecond lasers.
Employing the latest dielectric coating technology, these high-power laser mirrors provide minimum pulse distortion and the maximum usable bandwidth. When used with high-power femtosecond lasers operating at 750 to 850 nm, Optical Surfaces mirrors are designed for use at power densities exceeding 1 J/cm2 ...
Optical Surfaces Ltd. announce a new series of high-performance beam collimators designed for Modulation Transfer Function (MTF) testing of optical systems.
Benefiting from a lightweight design and new assembly technique - the LW-series of beam collimators uniquely combine high stability, high performance and short delivery time all at a market competitive price.
LW-series beam collimators incorporate a low expansion off-axis parabolic mirror, manufactured to better than lambda/10 p-v surface accuracy. The optics ...
Specialist high precision optics manufacturer – Optical Surfaces Ltd. (Kenley, UK) reports that despite the pressures of the global pandemic they managed to increase orders by 28% during 2020.
Highlights of the last year included being selected as the preferred optics supplier for two prestigious international projects, achieving on-time delivery to most existing customers and shipment of several complete systems which integrated precision optics and mechanics.
