Features
- A cube-type half mirror that can be ***d in a wide wavelength range from visible to infrared.
- It can be ***d for simple experiments and spectroscopic measurements.
- Since a metal film is ***d, the dep***ence 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 ***d 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 dep***ing on the absorption film.
- * When linearly polarized light such as laser light is ***d, the reflectivity and transmittance vary dep***ing on the polarization direction.
- * When adjusting the branching ratio to 1:1, tilt the polarization azimuth to 45 degrees or *** 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.
