Affordable, High Performance Beam Collimators

Affordable, High Performance Beam Collimators

Product News Wednesday, December 9, 2020: Optical Surfaces Ltd.

Optical Surfaces Ltd. announce a new series of high-performance beam collimators designed for Modulation Transfer Function (MTF) testing of optical systems.

Benefiting from a lightweight design and new assembly technique - the LW-series of beam collimators uniquely combine high stability, high performance and short delivery time all at a market competitive price.

LW-series beam collimators incorporate a low expansion off-axis parabolic mirror, manufactured to better than lambda/10 p-v surface accuracy. The optics within the beam collimator, are secured by the use of stress-free mounts and come pre-aligned for optimum performance. The off-axis design of LW-series beam collimators produces no central obscuration thereby ensuring highly efficient transmission is obtained.

The all-reflecting design of LW-series beam collimators is achromatic and with aluminium / magnesium fluoride coatings can operate from the UV to the infrared without adjustment. Using low expansion glass mirror substrates these beam collimators provide high operational stability and performance. Each system has an output port datum plane giving a defined distance to the focus. Each system is also supplied with an easy-to-use alignment aid to identify the centre of the focal plane. All LW-series beam collimators provide a 20mm field ensuring full compatibility with standard black bodies.

For further information on the LW-series of beam collimators for MTF optical testing please contact Optical Surfaces Ltd. on +44-208-668-6126 /

Optical Surfaces Ltd. has been producing optical components and systems for leading high-power laser research groups for many years. The company’s ISO 9001-2008 approved manufacturing workshops and test facilities are deep underground in a series of tunnels excavated in solid chalk where temperature remains constant and vibration is practically non-existent. With such stable conditions testing, particularly with long path lengths, becomes quantifiable and reliable. Working with these natural advantages is a highly skilled team of craftsmen with a commitment to excellence in both product quality and customer service.
