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.

Details

◦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.
