功能

• An unpolarized half-mirror that can be used in a wide range of visible or infrared light.
• It can be used for multiwavelength laser and polarization experiments of visible light.
• It is a hybrid film that combines a dielectric multilayer film and a metal film, and achieves both unpolarized light and broadband.
• 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.
• The reflection to transmission branching ratio (1:1) does not change when the polarization orientation of linearly polarized light changes.
• * Enter light from the prism side indicated by ○.
• * When light is inserted from the opposite prism, the reflectance and reflectance wavelength characteristics will be different.
• * The hybrid film is slightly absorbed by the metal film (10% to 15%).
• * Therefore, the total amount of transmitted light and reflected light is not 100%.
• * 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.
