Our Fiber collimators / focusers are designed for laser applications which require pure Gaussian beam. Holmarc Fiber Collimators are available from 5 mm to 40 mm aperture size. The output is very clean with no diffraction patterns or beam distortions. Output stays as Gaussian at any distance. Collimators are provided with FC / SMA connectors. Output is adjustable so that it can be tuned for best collimation at the wavelength and then can be locked down. Broadband anti-reflection coating is provided for visible region.
