Optical Surfaces Ltd reports how its proprietary smoothing techniques largely eliminate surface microcrack damage from the off-axis parabolic mirrors it produces for high-power laser applications. As a result, the achievable performance and operational lifetime of these critical focusing mirrors is enhanced. Surface microcracks introduced during machining processes such as grinding, can reduce the glass's intrinsic strength by creating stress concentration points. These defects not only...

Optical Surfaces Ltd has developed a novel kinematic mounting arrangement for its pre-aligned beam collimator and beam expander sub-assemblies. Traditionally large diameter or longer focal length optical systems require an extremely large, heavy and expensive reflective beam collimator system. Benefiting from a lightweight modular design - pre-aligned beam collimator kits from Optical Surfaces Ltd overcome these shortfalls. The introduction of kinetic mounting on these pre-aligned modules...

Optical Surfaces Ltd has supplied several sets of ultra-high quality plano-convex lenses to the MAX IV Laboratory to function as key focusing elements in diagnosing the beam in their state-of-the-art 3 GeV synchrotron storage ring. Based at Lund University (Sweden), the MAX IV Laboratory is an internationally renowned synchrotron facility providing scientists with the most brilliant X-rays enabling groundbreaking research in materials and life sciences using spectroscopy, diffraction,...

Optical Surfaces Ltd. is a leading manufacturer of large, high precision flat mirrors used in a wide variety of applications including beam steering, beam folding, interferometry and as optical components within imaging systems. Working in a thermally stable production environment – the experienced optical engineers at Optical Surfaces Ltd. can regularly achieve surface accuracies of better than ʎ/20 peak to valley on flats up to 750mm in diameter. Achieving high surface accuracy, top surface...

Optical Surfaces Ltd. has announced its reflective beam expanders are now available with the option to optimally operate in high vacuum environments, expanding or reducing high power laser beams. Benefiting from a high throughput off-axis design, these beam expanders provide an unobstructed output and highly efficient transmission. The reflective design of these beam expanders is achromatic and with different coatings they can operate from UV to far IR without adjustment. Vacuum compatible...
