Fiber Large Beam Collimators
Description
The LB20 Large Beam Fiber Collimator is a precision-engineered optical device designed for applications requiring highly collimated Gaussian beams and minimal optical aberrations. Operating at a nominal wavelength of 1550 nm, this fiber collimator delivers exceptional performance in a wide range of photonics applications including Lidar, Interferometry, Remote Sensing, Spectroscopy, and Biomedical systems.
Featuring an adjustable collimation mechanism and a compact, robust aluminum alloy housing, the LB20 collimator supports beam sizes up to 15 mm with a beam divergence of less than 0.5 mrad. Its low wavefront error (λ/10) and pointing error (<0.1 mrad) ensure superior beam quality and alignment precision. The device supports FC/APC receptacles and handles optical power up to 20 watts, making it suitable for both standard and high-power applications.
The LB20 is compatible with singlemode, multimode, and polarization maintaining fibers, and supports wavelengths from 350 nm to 2000 nm. Whether used with semiconductor lasers, fiber lasers, or broadband sources, it delivers reliable performance under operating temperatures from -5°C to +80°C.
