Laser beam expander datasheet

Datasheet describes laser beam expanders, including design features, high technical specifications and options for laboratories focusing on high power laser and Doppler shift Lidar applications.

Optical Surfaces has announced a technical datasheet that describes its range of high performance laser beam expanders.

Downloadable as a PDF file from the firm's web site, the datasheet describes the design features, high technical specifications and choice of options for laboratories focusing on high power laser and Doppler shift Lidar applications.

Made 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 the beam expanders is achromatic and with aluminium coatings can operate from ultraviolet to far infra-red without adjustment.

Using zero expansion glass mirror substrates, the beam expanders provide high operational stability.

They are housed in a box assembly that can be fixed 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.

Options let them be tailored to needs.

For applications demanding the highest reflectivity and high damage threshold, 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 100, 150 and 200mm with up to 20x magnification systems, with other magnification beam expanders built on request.

Horizontal and vertical beam displacements are offered, to customer choice.
