Variable Beamsplitter Light path corrector
VBS/WSQNA/WBNA
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.
Optics & Optical Coatings
- The veriable 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.
