High performance laser beam expanders feature diffraction limited optical designs with large output clear apertures of 1.3 mm to over 100mm, expansion ratios from 2X to 30X and input apertures of 1.3 mm to 20mm. The beam expanders have high transmission, low wavefront distortion and can be specified at single and dual wavelengths from 248nm to 1550nm. Damage thresholds are typically 500MW/cm2.
