Long Distance Collimator

The fiber optic beam can be collimated and shaped for different laser outputs through fiber optic connections, providing diffraction-limited performance at the design wavelength, with a collimation distance of up to 200 meters. The structure of this series of collimators is compact. Aberration correction is performed during design by selecting an air-spaced doublet lens series, which has an excellent collimation effect and can couple space light. The effective focal length of the double lens depends on the wavelength. Therefore, this series of collimators should be used at the design wavelength for optimal performance.
