PDBSH-25.4C1.5 Splitter

[Features]
· A polka-dot beam splitter is a beam splitter which has a dot pattern aluminum coating on its glass surface.
· There is little dependence on the incident angle, and it can be used with wavelengths over a broad range from the ultraviolet region to the infrared region.
· The reflective transmittance ratio is adjusted according to the area ratio of the coated points.
· In contrast to the dielectric type beam splitter, even changing the incidence angle will produce almost no change in the ratio of the reflectivity and transmissivity.
· Two outer diameters of φ25.4 mm and φ50.8 mm and three reflectance transmittance ratios of 7:3, 5:5, and 3:7 are available.
· * Diffraction occurs when used with a laser beam with high coherence.
· * With the incidence of light, scattered light will be caused by dots.
· * Transmittance at 45 degrees is expressed with the average values of P polarization and S polarization.
· * Optical path of the transmitted light may be shifted a few millimeters parallel from the incident light, depending on the refractive index and thickness of the substrate.
· * There is a chance it will not split according to the separation ratio if the diameter of the incident beam is extremely thin.
· * Do not wash with water, solvents, etc. This is a cause of surface deterioration.
· * Use in an environment with little dust and no condensation.
· * If dust or dirt adheres, use dry air to blow them away gently rather than breathing on them.
