Latest News  Illustrated Guide to Aligning Off-Axis ParaboloidsOptical Surfaces Ltd. announces that it produced an updated version of its popular 'Practical Guide to Off-Axis Paraboloid Alignment Procedures'. Off-axis paraboloids, also referred to as off-axis parabolic mirrors, provide the advantage of an unhindered aperture and access to the focal plane. They are ideal for broadband or multiple wavelength applications, thanks to their complete achromatic performance. Off-axis paraboloids often deliver the most cost-effective solution without compromising performance to many problems ... Precision Windows for High Power Laser ExperimentsBenefiting from an ultra-stable production environment and proprietary polishing techniques - Optical Surfaces Ltd. is able to routinely produce high-power laser windows up to 600mm in diameter with typical wavefront error of lambda/10 and surface finish of 40/20 to 10/5. Working with a range of optical materials including BK-7 and fused silica, which offer good homogeneity and transmission from the UV to the Near-IR, Optical Surfaces is today a preferred supplier ... Astronomical Research Drives Improvements in Optical TechnologyOptical Surfaces Ltd. has published an article 'Unveiling the Cosmos' that discusses the latest challenges and trends in modern astronomy and describes how these advances have acted as a significant driver towards the improvement of their optical technologies. Using new high homogeneity optical materials and improved polishing compounds has enabled Optical Surfaces to make further improvements in their manufacturing of large space optics with very tight manufacturing tolerances. Combining this with ... Beam Collimators for MTF Optical TestingOptical Surfaces Ltd is a leading supplier of Beam Collimators tailored to enable precise Modulation Transfer Function (MTF) testing of your optical systems. MTF is a trusted technique for objectively evaluating the image-forming capability of optical systems. Reflective beam collimators are mirror assemblies that take divergent or convergent incoming light rays and produce parallel light output. They can be used to replicate a target at infinity without parallax. As a consequence, ... |
