WHARTON, N.J. - April 22, 2008 -- Special Optics Inc., a Navitar company, has introduced a line of high-performance large-output laser beam expanders that include diffraction-limited optical designs with large output clear apertures of 10 to over 100 mm, expansion ratios from 5X to 40X, and input apertures of 1.3 to 20 mm.
With high transmission and low wavefront distortion, the large-output beam expanders can be specified at single and dual wavelengths from 248 to 1550 nm and have damage thresholds of typically 500 MW/cm2. Featuring standard clear entrance apertures of up to 20 mm, the beam expanders transmit the entire beam with excellent wavefront quality, the company said.
The beam expanders allow proper collimation and a more controlled focus or defocus of the beam. These Galilean-design beam expanders provide an adjustable focus for collimation at varying wavelengths which can be used for divergence correction, collimation and focusing. They are adaptable for complex applications requiring increased power density at the focal point, beam guidance over a long distance, dual wavelengths (1064 nm and 532 nm), high-power laser energy and large aperture needs.
Special Optics said its beam expanders are designed to be rugged and self-supporting and provide performance from the ultraviolet to the visible and infrared regions. With aluminum construction to minimize thermal distortion, the beam expanders are easy to use and provide accurate, unobstructed expansion for any collimated input source.
When used in combination with its f-Theta lenses, the large-output beam expanders can be used for a variety of laser processing and laser micromachining tasks, the company said, such as:
