• Polarization beam splitter designed for pulsed laser such as YAG laser.
• Since the adhesive is not used on the surface of the prism, it is joined by optical contact, it can withstand high-power laser.
• 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 separation can be achieved 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 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 ○.
• * Before use, make sure that the energy density of the incident laser beam does not exceed the laser capacity.
• * If the laser beam is narrowly narrowed by a lens or concave reflection, the energy density may exceed the laser capacity of the device and the device may be damaged.
• * The extinction ratio of reflected light is slightly lower than that of transmitted light. (Approx. 3/100)
• * 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.
