Beam Combiners are ideal for applications where diode
lasers are being used for system alignment. Designed for used at 45
degree, they transmit the long wavelength beam and align it with the 90
degree reflected diode beam.
The displacement of the output beam to the
incident beam is given by the following equation:
Where,
α is angle of incidence
n is index of refraction
t is thickness
d is displacement of the material
For example: BCZ-1-3, d=1mm; BCBK-1-3, d=0.8mm

We also provide beam combiner modules. Inside there is a
beam combiner. A red diode is vertically fixed and the laser beam (such
as 1064nm fiber laser) horizontally goes through the module. The model
of the modules is described as follows:
Part number: STH-xxxx-yy
STH � red beam combiner
xxxx � laser wavelength
yy - laser beam diameter
Our
standard beam combiner
STH-1064-12 is designed for the use with the
fiber lasers STR-P10, -P20 and �P30.
