Optimised Mounts for Wedged Back Mirrors

Optical Surfaces Ltd has launched a new mounting system that provides a highly stable platform for wedged back off-axis parabolic mirrors. Off axis parabolic mirrors can be produced by two distinct methods, as a standalone single optic or from a parent on-axis paraboloid.

Ultra smooth, high reflectance toroidal mirrors

Optical Surfaces Ltd. is a leading manufacturer of top-quality toroidal mirrors for spectroscopic and imaging applications. Toroidal mirrors are aspheric mirrors where the curvature of orthogonal horizontal and vertical axes is different. For optical products where a small, focused spot is needed, toroidal mirrors combine focusing and beam folding capabilities in a single element. This improves energy throughput, saving money, and allows for more compact designs. Toroidal mirrors also correct...

High precision Schlieren optics for aerodynamic testing

Optical Surfaces Ltd. is a leading producer of high precision mirrors and windows for Schlieren imaging applications in the Aerospace industry. Supersonic wind tunnels are commonly used by engineers to test and improve the aerodynamic performance of aircraft designs and engine components. During a test, the aircraft model is placed in the test section of a wind tunnel and air is made to flow past the model. Schlieren imaging is a trusted method for visualising density variations in these...

High power laser beam focusing

Using proprietary production techniques, and benefiting from an ultra-stable production facility, Optical Surfaces Ltd has established itself as a leading supplier of fast focusing on-axis parabolic mirrors for high power laser experiments. Inherently on-axis parabolic mirrors allow a higher f-number (<0.7) to be achieved than off-axis designs therefore more laser energy can be concentrated on an experimental target. Generally, alignment of on-axis parabolic mirrors is less critical, thus...

Beam collimator kit transforms testing of military optical systems

Optical Surfaces Ltd has developed a new approach, using a series of pre-aligned beam collimator sub-assemblies, for Modulation Transfer Function (MTF) testing of large diameter military optical systems. MTF is a technique, trusted by optical designers, for objectively evaluating the image-forming capability of military optical systems. As reflective beam collimators can be used to replicate a target at infinity or interim distances without parallax, they are the device of choice for...

Spectrograph optics for astronomical telescopes

Optical Surfaces Ltd is a leading producer of ultra-high precision optical components and systems for telescope spectrographs. The main function of a telescope spectrograph is to separate light into its component colours (or wavelengths) to reveal information about the chemical content, temperature and motion of distant planets, comets, stars, interstellar gas clouds and galaxies. Benefiting from a unique underground facility, where temperatures remain constant year-round and vibration is...
