Minimal Alignment Reflecting Collimators...

A new technical datasheet that describes its range of high performance Reflecting Tube Collimators has been announced by Optical Surfaces Ltd. - specialists in high precision optics and optical systems.

Downloadable as a pdf. file from www.optisurf.com/frame6.htm the datasheet describes the design features, high technical specifications and wide choice of options that have made the OSL range the tube collimators of choice for many laboratories worldwide. Typical applications for OSL tube collimators include MTF testing, optical resolution testing, star simulation, MRTD testing and bore-sighting for alignment / inspection of customer systems.

Manufactured to better than lambda/10 p-v surface accuracy, the off-axis design of OSL Reflecting tube collimators produces no central obscuration and highly efficient transmission is obtained. All optics within the tube collimators come pre-aligned in stress-free mounts. To facilitate ease of use each of the tube collimator's three feet is adjustable by +/- 10mm for centre height positioning. Unlike other collimator solutions, the new Optical Surfaces range is transportable from site to site whilst maintaining alignment.

The all-reflecting design of OSL beam expanders is achromatic and with aluminium / magnesium fluoride coatings can operate from the UV to the infrared without adjustment. Using zero expansion glass mirror substrates OSL tube collimators provide exceptional operational stability. Each system has an output port datum plane giving a defined distance to the focus. All collimators provide a 20mm field ensuring full compatibility with standard black bodies.

A wide choice of options enables OSL beam collimators to be optimally tailored to suit your exact needs. For applications demanding the highest reflectivity and high damage threshold, ultra-hard dielectric, protected silver and gold laser coatings are available. For applications requiring operation over a wide temperature range athermalised beam collimators can be supplied. Standard models include exit apertures of 100mm, 120mm, 150mm, 200mm, 240mm and 300mm. Customised systems can be supplied with larger field sizes, different output interfaces and platforms. Other options include reticle holders, lamphouses and black bodies.

Test interferogram and analysis, showing wavefront accuracy, focal length and working distance, are supplied with every reflecting tube colimator supplied by Optical Surfaces Ltd. Optical Surfaces ISO 9001-2000 approved manufacturing facility provides the flexible resources to supply from single specialist requirements to OEM quantities.
