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…

Highly Smooth Off Axis Parabolic Mirrors Offer Near 100% Reflectance

Optical Surfaces Ltd. reports that its off-axis parabolic mirrors are particularly suitable for coating using an Ion Beam Sputtering (IBS) technique that provides near 100% reflectivity thereby providing unmatched protection from thermal damage that often arises from high power continuous wave lasers. Dr Aris Kouris, Sales Director of Optical Surfaces Ltd. explained "Surface microroughness of parabolic mirrors is an important optical quality parameter which describes features which are typically smaller than ...

Light Weighted Mirrors

Light Weighted Mirrors

Optical Surfaces Ltd has developed proprietary light weighting techniques that can reduce the weight of a mirror by as much as 60%. In spaceborne applications the need to minimise payload is a key factor in designing optical systems. Optical Surfaces lightweight mirrors are designed to provide sufficient rigidity to ensure ultra-high precision optical performance while reducing the overall weight of the mirror. This reduced weight, in turn, allows smaller, lighter support ...
