Product Details Supplier Info More products

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 for high frequency 50-fs pulses without deterioration.

Benefiting from a uniquely stable production and testing environment – Optical Surfaces skilled craftsmen routinely produce high power laser mirrors of the highest quality and precision. Produced from materials including glass, ceramic, and silica – Optical Surfaces off-axis parabolic mirrors are designed to optimise the performance of rapid-pulsed high-power lasers. All surface accuracies are checked by interferometer and are guaranteed to meet lambda/10 p-v wave accuracy with low scatter. The quality and performance of large diameter, high power femtosecond laser mirrors from Optical Surfaces Ltd. is second to none.

Typical applications for these extremely durable high-power femtosecond laser mirrors includes plasma physics, laser manufacturing and telecommunications.

Optical Surfaces Ltd. has been producing optical components and systems for leading high-power laser research groups for many years. The company’s ISO 9001-2008 approved manufacturing workshops and test facilities are deep underground in a series of tunnels excavated in solid chalk where temperature remains constant and vibration is practically non-existent. With such stable conditions testing, particularly with long path lengths, becomes quantifiable and reliable. Working with these natural advantages is a highly skilled team of craftsmen with a commitment to excellence in both product quality and customer service.

Optical Surfaces

Optical Surfaces Ltd has been producing large and demanding high-precision optical components and systems for more than 40 years and is today internationally acknowledged for its technical expertise, attention to quality and customer service.

With the main workshops and test facilities deep underground in an area excavated from solid chalk, temperatures remain constant year-round and vibration is practically non-existent. These are important considerations when making, mounting and testing high-precision optics. Working with these natural advantages Optical Surfaces Ltd is able to supply high-precision off-axis parabolas, spherical and flat mirrors, etalons, aspherics, reference flats, windows, collimators and beam expanders for the most demanding applications. With such stable conditions, testing, particularly with long path lengths, becomes quantifiable and reliable. Investment in large-aperture Fizeau, Zygo GPI, Flashphase, Twyman Green, Scatterplate, and Laser Unequal Path interferometers allows detailed testing of the largest-diameter optics. Topographic and fringe analysis provides precise testing of surface roughness and confirms the wavefront of various surface forms. A rolling programme for calibration of test optics where possible to national standards and production approval to ISO 9001-2008 ensure that the quality of optics from Optical Surfaces is second to none.

Today the company is a trusted supplier to leading scientific, astronomical and defence establishments including many space projects worldwide.
