Large Beam Fiber Optical Collimator(Working wavelength: 532nm-1650nm)-CLA Series


Fiberoptic collimators come in all sizes commercially. Most of them are based on the successful GRIN lenses, which find their way into many passive and active components. However, GRIN lenses are not very suitable for visible wavelengths or large beam. Our high performance collimators employ high quality aspheric lenses and achromatic doublets to achieve low wave-front distortion, low divergence, and diffraction limited beam quality.


 


Large-beam collimators are not only ideal for long-range target shooting but also good for pair coupling at long working distances. Some of our very large-beam (>14 mm) collimators have been used in free-space optics communications. Use these collimators with our standard


laser-diode light source, pigtailed diode lasers, or receptacle laser diode modules. Rayscience also produces custom retro-reflectors to pair with our collimators.
