Large Output Beam Expanders

Special Optics line of large output beam expanders provide diffraction limited performance over the entire 100 mm aperture, and deliver low wavelength distortion and high transmittance over a broad spectral range.  They feature adjustable focus for collimation at various wavelengths, broadband antireflection 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, 1/8, or 1/10th 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, 1/8 or 1/10th Wavefront Distortion can be achieved.  Please call or email us for this request.
