Beam splitter

Features

This is an optical component that separates transmitted light and reflected light at the desired ratio. It is also possible to separate P-polarized and S-polarized light from incident light (PBS: Polarizing Beam Splitter) and to produce a type with less polarization dependence (N-PBS: Non-Polarizing Beam Splitter).

Applications

Laser processing machines, measuring instrument, semiconductor exposure apparatus, FPD exposure apparatus and cameras

Example characteristics

PBS（Polarization Beam Splitter）

Cube type
Two rectangular prisms are bonded together and a dielectric multilayer film is applied to the slope of one prism to separate the P- and S-polarized components. It separates a single wavelength of the near-infrared region from the ultraviolet region, and the P- and S-polarized components of the visible region.
We design the wavelength, angle of incidence and extinction ratio to meet customer requirements. We also accept orders for optical contact lenses.

Plate type
By applying a dielectric multilayer film onto a substrate, it is possible to separate the P- and S-polarized components of a single wavelength or narrow range of wavelengths within the wavelength range from the ultraviolet region to the near infrared region. We design the wavelength, angle of incidence and extinction ratio to meet customer requirements. It has excellent light and heat resistance and is suitable for laser applications.

BS（Beam Splitter）

By applying a dielectric multilayer film onto a substrate, it is possible to separate specific wavelengths in two directions at the desired ratio within the wavelength range from the ultraviolet region to the infrared region.
We design the wavelength, angle of incidence and extinction ratio to meet customer requirements.
