Collimator Lens for Laser

Laser collimator is one of the core components of fiber laser cutting machine, marking machine, welding machine and other laser equipment. Different optical elements allow optimization of beam collimation for different measurement processes. In order to improve the fiber coupling efficiency and reduce the beam divergence angle, a fiber collimator needs to be installed at the fiber port.

Product Description

Features of collimator lens for laser

● The beam is highly collimated. After being adjusted by the fiber collimator, the divergence angle of the beam does not exceed 2°.

● Good consistency, the working distance consistency is greater than 99%.

● The laser light transmittance is high, the reflectivity is low, and the threshold value of anti-laser damage is high, which can be applied to 20000W laser.

● The laser collimation effect is good, less than 1/10 wavelength.

● The film has good density and long service life.
