기능

• A cube beam splitter with 1:2 or 1:3 reflectivity and transmittance.
• Combined with a half mirror, it can be a three-branch or four-branch optical system that distributes light equally.
• Accurate branching characteristics can be obtained in wide wavelength bands of white and visible 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 ○.
• * The spectral wavelength characteristics may differ when light is inserted from the opposite prism.
• * When linearly polarized light such as laser light is used, the reflectivity and transmittance vary depending on the polarization direction.
• * When strictly adjusting the branching ratio, 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.
• * In addition, chromatic aberration and spherical aberration may occur when a converging or diverging beam is injected.
