Light path corrector / WSQNA-50S03-1-266-0/45D

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.

Part Number
◦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.

Guide ▶Different size
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.
