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.
