Features

• This is a beam splitter that reduces the thickness of the substrate to the extreme.
• Reflected light can be extracted without affecting the beam shift or wavelength dispersion of transmitted light when inserted into the optical path.
• Two types of glass substrates, 300 μm and 90 μm in thickness, are available.
• The substrate is coated with a dielectric multilayer film that branches transmission and reflection 1:1.
• 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.
• The thin glass substrate is firmly fixed to the holding glass, which is less affected by thermal expansion.
• Unlike pellicles, synthetic quartz is thinly processed, so it has excellent durability and vibration resistance.
• * Since the glass substrate of the plate thin beam splitter is very thin, it will be damaged only by light force.
• * Handle with care.
• * If dust arrives on the surface of the device, it cannot be wiped with lens paper, etc.
• * Use an air blower to blow away the garbage.
• * 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.
• * Transmittance wavelength characteristics change when used at an incidence angle other than 45 degrees.
• * The reflecting surface may be distorted when the holding glass is pressed tightly.
• * When fixing, be sure to support only the outer frame.
• * The surface accuracy of the reflecting surface may deteriorate when the camera is used in an environment where temperature changes rapidly.
• * 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.
