SIGMAKOKI Polarizing Beamsplitter 1064nm 20mm　PBS-20-10640

Feature

• Polarization beam splitter with a high extinction ratio that matches the wavelength of various lasers.
• It can be used for various polarization experiments using monochromatic lasers.
• By transmitting P-polarized light and reflecting S-polarized light, the polarization state of the incident light can be divided into orthogonal components.
• Since a dielectric multilayer film is used for coating, light loss is small and polarization can be separated efficiently.
• Since it is a cube type, the optical axis of the emitted light will not be translated if the beam is incident perpendicularly. Also, even if a beam of the same size as the effective diameter is injected, the transmitted or reflected light will not be lost or reduced.
• A plate-type polarization beam splitter (PBS-C) is also available.
• A Grantomson Prism (GTPC) with a high extinction ratio is also available.
• * The characteristics of transmittance and extinction ratio may change if light enters from the prism side which is not marked with ○.
• * The extinction ratio of reflected light is slightly lower than that of transmitted light.
• * Transmittance and extinction ratio will be poor when using at wavelengths other than the applicable wavelength.
• * Wavelength dispersion occurs in transmitted and reflected light due to the refractive index of the material and the thickness of the glass. In addition, chromatic aberration and spherical aberration may occur when a converging or diverging beam is injected.
