HS-419 Foot Switch

[Features]
· Dielectric multi-layer mirror available in a lineup of various wavelengths and possessing extremely high reflective characteristics.
· Laser line dielectric multilayer film mirror with reflection zones matching various laser wavelengths.
· Achieves a high degree of reflectance, so that even if multiple mirrors are reflected, the loss is small; ideal as a mirror for steering laser beams.
· 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.
· When using at an incident angle of 0° or 45° or less, use the 0°-45° propagating film plane mirror (TFVM).
· 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.
· * Reflectance may decrease when used with an incident angle other than 45°.
· * When used at incompatible wavelengths, the reflectance may decrease.
