         Products             Beam Combiner
 

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.
