532nm-Aspheric Fiber Collimator

The CMA series of receptacle-style fiber collimators adopt AR-coated aspheric lenses with focal lengths ranging from 4mm to 18mm, mounted inside non-magnetic stainless steel housings with receptacles for FC/PC, FC/APC or SMA fiber optic connectors. Each collimation package is factory aligned to provide diffraction-limited performance for wavelengths ranging from 405 nm to 1550nm. Although pre-aligned at specific wavelength in factory, we still reserve screw in the package for fine tuning the distance between fiber end-face and collimating optics when customers have the need to switch the wavelength. These collimators are suitable for single-mode fiber cables leading to collimated beams with a Gaussian intensity profile.
