SIGMAKOKI Frameless beam splitter unit 400-700nm

The frame of the mirror holder has been eliminated, and the entire front of the holder is made of mirror. The substrate is made of ceramic with a low thermal expansion coefficient, which is polished with high precision, resulting in extremely high surface accuracy and temperature stability. A lineup is available that can be used with various wavelengths of YAG lasers. The mirror type is coated with a dielectric multilayer film on a highly polished ceramic, so it is comparable to a dielectric multilayer film mirror coated on glass. The effective area of the mirror has been expanded to the maximum extent, and a compact mirror adjustment mechanism has been achieved. The reflected wavefront does not collapse due to temperature changes, making it ideal for precision optical systems. This product guarantees the surface accuracy after coating (in the holder state). It has high laser damage resistance and can be used with high-power lasers. The company obtained a patent for this product in November 2011. The method of mounting to the base is the same as the MHG mirror holder. It can be attached to the post stand PST-** (sold separately) and rod RO-** (sold separately). *The reflectance wavelength characteristics of the dielectric multilayer film change depending on the polarization state of the incident beam. *P polarization has a lower reflectance and a narrower reflection band than S polarization. *Reflectance in the specifications is the average reflectance of P-polarized light and S-polarized light. *Reflectance may decrease if used at an incident angle other than 45°. *Reflectance may decrease if used at a wavelength other than the applicable wavelength. *Surface accuracy guarantee data is not included with the product.
