Lens, Mirror for Fiber Laser & YAG Laser
Beam Splitter
Feature
The diffractive beam splitter is a DOE, Diffractive Optical Elements, that splits laser light into multiple beams and realizes simultaneous focusing on multiple points by combining lenses. Various beam intensity patterns are formed by line or matrix distribution.
●Can be used in conjunction with a multi-mode laser as well as with a single-mode.
●Offers easy alignment, splitting characteristics do not depend on beam incidence position.
●Spot pitch is proportional to the focal length of focusing optics.
●Moving parallel to the scanning in-line beam spots parallel to their sequence can achieve deep penetration.
●Spot pitch adjustment is possible by positioning the Diffractive Beam Splitter after the focusing lens.
●Pitch adjustment of multi-point scribing is possible by rotating the Diffractive Beam Splitter.
