Polka dot beam spliter 25.4mm Diameter 50:50

PDBSH-25.4C1.5

The polka dot beamsplitter is a beamsplitter that has aluminum coating of halftone dots (polka dots) on the glass substrate. It has a low dependence on the incident angle and can be used in a wide range of wavelengths from ultraviolet region to the infrared region.
◦Reflectance to transmittance ratio is manufactured by adjusting the area ratio of the points that have been coated.
◦Unlike dielectric beamsplitters, the polka dot beamsplitter reflectance and transmittance ratio does not change as the incident angle changes.
◦There are two sizes available φ25.4mm and φ50.8mm diameter and three types of reflectance to transmittance ratio, 7:3, 5:5 and 3:7.

Remark -
Attention
  • When used with a laser beam with high interference, diffraction occurs.
  • When light is incident, scattering light by the halftone dot occurs.
  • By the effect of the refractive index and the thickness of the substrate, the optical path of the transmitted light over the incident light will move by 0.5 extent parallel.
  • When the incident beam diameter is very thin, it is not possible to separate into the split ratio.
  • Do not clean with water or solvents. It may cause surface deterioration.
  • Please use in the environments which are non-condensing and less dust. If the dust or dirt is deposited, please do not blow but blow it off gently with dried air.
