HS-401 Hot Tweezers

[Features]
· Mirror with high reflectance that broadly covers the ultraviolet or infrared ranges in addition to the visible range.
· It can be used for spectroscopic experiments including invisible light and propagation of black body radiation spectrum.
· Higher reflectance than metal film mirrors can be obtained even in ultraviolet and infrared areas.
· As a dielectric multilayer mirror, its mirror surface is not easily scratched and can be cleaned.
· Because the film is not absorbent, it does not change over time and can withstand continuous laser irradiation.
· A surface accuracy guaranteed mirror (HTFM) that guarantees its surface accuracy after coating is also available.
· * 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.
· * Mirror surface has metallic gloss, but does not use metal.
· * Be careful to avoid confusion with metal film mirrors.
