Special Optics line of large output beam expanders provide diffraction limited performance over the entire 100mm aperture, and deliver low wavelength distortion and high transmittance over a broad spectral range. They feature adjustable focus for collimation at various wavelengths, broadband anti-reflection coatings, large output and input apertures and a diffraction limited Galilean design. Wavefront distortion is standard at less than 1/2 wave, but 1/4 or 1/8 wavefront distortion can be achieved upon request. Custom systems have been designed to provide output beam diameters of over 200mm as well as input beam diameters that exceed 100mm.
Note: 1/4 or 1/8 wavefront distortion can be achieved. Please call or email us for this request.
