Off-Axis Paraboloids Enhance Laser Power Density

Enhance Laser Power DensityOff-axis parabolic mirrors can be a useful tool in optical design. OAPs combine the achromatic and diffraction limited imaging properties of a parabolic mirror with the ability to deviate the light path off-axis, which is useful for most imaging systems. OAP’s offer the ability to focus collimated light without introducing spherical aberration. Continue…

Each small diameter mounted off-axis parabolic mirror comes in a protective carrying case

Versatile Mounting System for Off-Axis Parabolic Mirrors

Optical Surfaces Ltd has launched a new low profile mounting system that provides a highly stable platform for smaller diameter (up to 75mm) parallel or wedge backed off-axis parabolic (OAP) mirrors. Designed to facilitate rapid and simple mounting onto an optical table or other support, Optical Surfaces is now able to supply smaller diameter OAP mirrors pre-aligned in the new high quality stress-free mount. Benefiting from a uniquely stable manufacturing environment, and ...

Highly Efficient Fibre Optic Channel Plates

Optical Surfaces Ltd reports how it is machining and polishing high precision Fibre Optic Channel Plates (FOCP) for an X-ray shielding application. Fibre Optic Channel Plates are widely used as optical devices to replace optical lenses because they require no focusing distance making them an ideal component when creating a compact optical device. Comprising a bundle of micron-sized optical fibres - FOCP are used as a lens to transmit light or ...
