Low profile mount offers stable platform for large mirrors

Optical Surfaces Ltd. has developed a new low profile mirror mount that provides a secure platform for large and heavy high-precision flat, spherical, on-axis and off-axis mirrors. Robustly designed in black anodized aluminium, the mount can be tailored to match the size and shape of the mirror in a compact low-profile envelope.To enable optimisation of alignment the mount allows fine adjustment of mirror rotation. In addition, angular alignment (tip and tilt) of mounted mirrors is achieved...

High stability beam collimators for military optics testing

Optical Surfaces Ltd has supplied two reflective beam collimators to a leading European supplier of high precision optics to military and defence contractors. Reflective beam collimators are mirror assemblies that take divergent or convergent incoming light and produce parallel output. They can be used to replicate a target at infinity without parallax. Consequently, reflective beam collimators are the device of choice for performing Modulation Transfer Function (MTF) measurements over...

Custom Off-Axis Paraboloids

Optical Surfaces Ltd is a leading international producer of large diameter prototype and custom Off-Axis Paraboloids (OAPs) that deliver outstanding performance. Benefiting from an ultra-stable manufacturing environment, and employing proprietary production techniques, Optical Surfaces highly skilled engineers are world renowned for producing OAP mirrors with unmatched surface accuracy, quality, and slope errors. Off-Axis Paraboloids, also known as off-axis parabolic mirrors, are commonly used...

High magnification of small diameter laser beams

Optical Surfaces Ltd. has developed a proprietary artifact suppression method allowing them to design and produce a novel high magnification reflective beam expander for small aperture laser applications. Accurate high magnification of small aperture laser beams has traditionally been a challenge because the optics associated with such a beam expander are difficult to test using an optical interferometer. This is because small aperture laser beams, when highly magnified, generate artifacts...

High resolution imaging of astronomical objects

Optical Surfaces Ltd reports that it has received a follow-up order from Magdalena Ridge Observatory (MRO) to produce three second generation off-axis beam compressors to expand the capabilities of the facility's optical interferometer. The Magdalena Ridge Observatory Interferometer (MROI) project's mission is to develop a ten-element imaging interferometer to operate at wavelengths between 0.6 and 2.4 microns with baselines from 7.8 to 340 meters. The technical and scientific goals of the...
