คุณลักษณะ

• A mirror for use in high-energy pulsed Nd-YAG laser (or Yb-YLF laser) and excimer laser optics.
• Mirrors ranging from the fundamental wave (1064 nm) to the 4 times wave (266 nm) and mirrors for Ar* F (193 nm) and Kr* F (248 nm) excimer lasers are available according to the wavelength of the YAG laser.
• High reflectivity is obtained, so light intensity is not greatly attenuated when multiple mirrors are reflected.
• Since it uses a dielectric multilayer film without absorption, it can withstand continuous irradiation by a high-power laser.
• The laser capacity was tested 200 on 1 in accordance with ISO21254.
• We also have a Surface Accuracy Guarantee Mirror (HTFM) that guarantees surface accuracy after coating.
• * Before use, make sure that the energy density of the incident laser beam does not exceed the laser capacity.
• * If the laser beam is narrowed by a lens or concave reflection, the energy density may exceed the laser capacity and the mirror may be damaged.
• * When the light intensity of the incident beam is large, the beam may pass through the mirror (transmission ratio is 1% or less).
• * Be sure to use a light shielding plate on the rear side of the mirror to block stray light.
• Ultraviolet mirrors may emit fluorescence.
• * Reflectance wavelength characteristics of dielectric multilayer films vary depending on the polarization state of the incident beam.
• * P-polarized light has a lower reflectivity and a narrower reflection band than S-polarized light.
• * The reflectance of the specification is expressed as the average value of the reflectance of P-polarized light and S-polarized light.
• Reflectivity may be low when the watch is used at wavelengths other than the adaptive wavelength.
