GMMUHP-49-532 Mirror Unit

[Features]
· The frame of the mirror holder has been eliminated to enable a holder in which the entire front surface is a mirror.
· The substrate is made of ceramic with a low thermal expansion coefficient, with high-precision polishing to ensure extremely high surface accuracy and temperature stability.
· A selection of products is available for use with various YAG laser wavelengths.
· Because the mirror type is high-precision polished ceramic that has been coated with a dielectric multilayer film, it is not inferior to glass coated dielectric multilayer mirrors.
· A compact mirror adjustment mechanism is achieved by expanding the effective area of the mirror to the absolute limit.
· As the reflection wavefront does not break down due to temperature change, it is ideal for high-precision optical systems.
· This product guarantees the surface accuracy after coating (with holder).
· Laser yield strength is high, allowing use with high power lasers.
· A patent related to this product was acquired by this company in November 2011.
· The base mounting method is the same as that for the MHG mirror holder.
· Post stand PST-** (sold separately) and rod RO-** (sold separately) can be installed.
· * Reflection wavelength characteristics may vary depending on the polarization state of incident beams for dielectric multi-layer film.
· * P polarization has lower reflectance and a narrower reflection band than S polarization.
· * Reflectance for the specification shows average reflectance values of P polarization and S polarization.
· * Reflectance may decrease when used with an incident angle other than 45°.
· * When used at incompatible wavelengths, the reflectance may decrease.
· * No surface accuracy guarantee data is included with this product.
