기능

• A cube-type half mirror that can be used in a wide wavelength range from visible to infrared.
• It can be used for simple experiments and spectroscopic measurements.
• Since a metal film is used, the dependence of transmittance on wavelength is small over a wide wavelength range, and the transmittance and reflectivity hardly change when the wavelength changes.
• We have a lineup for visible and infrared light (semiconductor laser).
• 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 chromium film absorbs about 40% of the light, and only about 30% of the incident light can be used for transmitted light and reflected light.
• * Enter light from the prism side indicated by ○.
• * When light is inserted from the opposite prism, the reflectance and reflectance wavelength characteristics will differ depending on the absorption film.
• * When linearly polarized light such as laser light is used, the reflectivity and transmittance vary 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.
