Variable Plate Beamsplitter Synthetic Fused Silica 50x50mm 266nm

VBS-50S03-1-266

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.

Guide
  • Different size, wavelength and deviation not mentioned on-line or in our catalog are available as custom product upon on request.
  • WEB Reference Catalog Code/W3802
  • We offer the most comprehensive range of beamsplitter holders and stages to select from. Let us know the angle of your choice.
  • This variable attenuator (model SVAB) can be used in a system and is available.
Remark -
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.
