Fitur

• Half mirror for ultraviolet laser and YAG laser.
• We offer a wide range of wavelengths from vacuum ultraviolet to infrared.
• The surface is coated with a dielectric multilayer film and the back is coated with an anti-reflection film, resulting in little loss of light.
• There are two types: a parallel plane type, in which the beam does not refract, and a wedge type, in which ghosts and interference due to backside reflections are less affected.
• Since it is a plate type, wavelength dispersion and chromatic aberration generated by transmission through the substrate are small, and weight can be reduced.
• Ultra-wideband, wideband, and cube types are also available separately.
• The wedge type has an arrow pointing toward the surface at the thickest point.
• * 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 to 1:1, tilt the polarization azimuth to 45 degrees or use circularly polarized light.
• * Due to the effect of the refractive index and thickness of the substrate, the optical path of the transmitted light is translated by several millimeters relative to the incident light. (In the case of the wedge type, the beam polarization angle of about 30 minutes is added to the translation of the optical path.) * * The transmittance wavelength characteristic changes when used at an incident angle other than 45 degrees.
• * If the reflective coating surface cannot be identified, check with the arrow on the side of the substrate.
• * 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.
