คุณลักษณะ

• A cube-type half-mirror that splits unpolarized light, such as a white light source or an LED light source, equally between transmitted and reflected light.
• Accurate branching characteristics can be obtained in wide wavelength bands of white light and LED light sources.
• Since a dielectric multilayer film is used for coating, light loss is small and light can be efficiently separated.
• Since it is a cube type, the optical axis of the emitted light will not be translated if the beam is incident vertically.
• 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. *Enter light from the prism side marked with ○.
• * Reflectivity and reflectance wavelength characteristics may differ when light is inserted from the opposite prism.
• * When using linearly polarized light such as laser light, the reflectivity and transmittance vary greatly depending on the polarization direction.
• * When adjusting the branching ratio to 1:1, tilt the polarization azimuth to 45 degrees or use circularly polarized light.
• * The phase difference of the incident light is not stored in transmitted light or reflected light.
• * Use a wave plate to compensate for the phase difference.
• * Wavelength dispersion occurs in transmitted and reflected light due to the refractive index of the material and the thickness of the glass.
