功能

• This half mirror provides an accurate 1:1 divergence ratio between reflection and transmission even for laser and linearly polarized light sources.
• Dielectric multilayer film and transparent adhesive are used for the reflecting surface, and anti-reflection coat is used for the incoming and outgoing surfaces, so light loss is small and incident light can be used efficiently.
• The reflection to transmission branching ratio (1:1) does not change when the polarization orientation of linearly polarized light changes.
• We have a lineup that supports lasers of various wavelengths.
• 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 indicated by ○.
• * Reflectivity, branching ratio, and polarization characteristics may change when the other prism is used.
• * 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.
