  • Large-Beam Fiber Collimators
Aug 2007
Micro Laser Systems Inc.Request Info
Designed for use with single-mode polarization-maintaining fibers and fiber lasers, these collimators will generate a diffraction-limited beam with Gaussian profile at any distance along the path.

Aperture sizes from 5 mm to 45 mm allow for beam sizes ranging from approximately 2 mm to 35 mm. Fine focus adjustment allows you to tune for your wavelength of use and obtain wavefront errors <1/10 wave.

All collimators have receptacle for FC or FC/APC terminated fibers. Three wavelength regions cover the span from 370 nm to 1700 nm. There is no epoxy along the optical path, so these collimators can accept very large laser powers.

All standard collimators are stocked for quick shipment. Custom collimators have been made for harsh environments such as vacuum, airborne, radiation fields, high magnetic fields and space. Pigtailed, fixed focus and various beam sizes are also available.

1. A bundle of light rays that may be parallel, converging or diverging. 2. A concentrated, unidirectional stream of particles. 3. A concentrated, unidirectional flow of electromagnetic waves.
An optical instrument consisting of a well- corrected objective lens or mirror with a light source and or object/image (i.e. illuminated slit or retical) at its focal plane. Collimators are used to calibrate and align optical devices and elements, determine focal lengths, as well as replicate and project an source/object or image to infinity.  
As a wavefront of light passes by an opaque edge or through an opening, secondary weaker wavefronts are generated, apparently originating at that edge. These secondary wavefronts will interfere with the primary wavefront as well as with each other to form various diffraction patterns.  
The technology of generating and harnessing light and other forms of radiant energy whose quantum unit is the photon. The science includes light emission, transmission, deflection, amplification and detection by optical components and instruments, lasers and other light sources, fiber optics, electro-optical instrumentation, related hardware and electronics, and sophisticated systems. The range of applications of photonics extends from energy generation to detection to communications and...
