The adjustable aspheric fiber optical collimator developed by CSRayzer is used to collimate the light output by the optical fiber cable of FC/APC or FC/PC connector. The aspheric lens has chromatic aberration, and its effective focal length (EFL) is related to the wavelength, which provides diffraction limit at the designed wavelength and has good achromatic effect. It is very suitable for optical fiber coupling applications.

Each collimator is pre-aligned before leaving the factory, and in order to reduce surface reflection, both sides of each lens are coated with antireflection films. The collimator is compact in structure design and convenient for integration and installation. At present, it can provide typical wavelengths such as 405nm, 532nm, 543nm, 633nm, 780nm, 852nm, 980nm, 1064nm and 1550nm according to customer requirements.
