Challenging Aspheric Lenses for Nuclear Research

Challenging Aspheric Lenses for Nuclear Research

Optical Surfaces Ltd announces that it has received an order from the UK Atomic Weapons Establishment (AWE) for twelve ultra-fast focusing 370mm diameter aspheric lenses for its Orion petawatt laser research facility. World-class expertise and cutting-edge science, engineering and technology lie at the heart of AWE work, spanning the life cycle of nuclear warheads from initial concept and design, to final decommissioning and disposal. The Orion laser facility is used to conduct ...

Athermalised Beam Expanders for Challenging Applications

Athermalised Beam Expanders for Challenging Applications

For beam focusing applications in environments subject to wide temperature variation, Optical Surfaces Ltd. is able to produce athermalised beam expanders that deliver stable high performance. Optical Surfaces athermalised beam expanders are based upon a Dall-Kirkham off-axis mirror design that incorporates INVAR elements to provide thermal stabilisation. In addition, to better control thermal behaviour, the off-axis mirrors in the athermalised beam expanders have a short focal length resulting in a very ...

Beam Collimators for MTF Optical Testing

Beam Collimators for MTF Optical Testing

Optical 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, ...
