Optical Surfaces, a specialist in high precision optics and optical systems, has announced a new technical datasheet that describes its range of high performance laser beam expanders
Downloadable as a pdf file, the datasheet describes the design features, high technical specifications and wide choice of options that have made the OSL range the beam expanders of choice for many laboratories focusing upon high power laser and Doppler shift Lidar applications.
Manufactured to better than lambda/10 surface accuracy, the off-axis design of OSL beam expanders produces no central obscuration and highly efficient transmission is obtained, unspoilt by spider diffraction patterns.
Alignment aids are supplied with each beam expander to ensure correct beam pointing.
The all-reflecting design of OSL beam expanders is achromatic and with aluminium coatings can operate from the UV to far IR without adjustment.
Using zero expansion glass mirror substrates OSL beam expanders provide high operational stability.
OSL beam expanders are housed in a convenient box assembly that offers provision for fixing to an optical table and enables transportation to different sites without the need for internal realignment.
Test interferograms and an OPD map are supplied with every beam expander supplied by Optical Surfaces .
A wide choice of options enables OSL beam expanders 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 expanders can be supplied.
Standard models include exit apertures of 100mm, 150mm and 200mm with up to 20x magnification systems, with other magnification beam expanders built upon request.
Both horizontal and vertical beam displacements are offered, to customer choice.
Optical Surfaces ISO 9001-2000 approved manufacturing facility provides the flexible resources to supply from single specialist requirements to OEM quantities.
