With a variable beamsplitter, the incident angle of a laser can be changed. The (R:T) ratios can also be modified. This is commonly used to adjust the light intensity of the laser without a variable adjustment of the light intensity or the laser to be stabilized.
◦The variable beamsplitter has a dielectric multilayer coating which has excellent durability and light resistance. ◦The beam shift caused by the tilt of the beamsplitter can be removed by using a correcting plate. (See how to use) ◦It can be used for arbitrary polarization. However, the transmittance characteristic depends on the polarization.
Different size, wavelength and deviation not mentioned on-line or in our catalog are available as custom product upon on request.

Attention
When using with high power laser, make sure to execute at the end edge of the reflected light.
The reflectance properties of the optics may change in a high temperature environment.
When adjusting the transmittance, the incident angle may change and cause the light path to shift. To correct this, please use the light path corrector (model WSQNA/WBNA)
For a large beam size of 30mm diameter or larger and used it at a high inclination level, the beam can be cut at the reflected area.
For “P” polarization use, make sure that the incident angle is at 45 degrees or more.
