Ultraviolet HR Silica Optical Mirrors 10-5 Scratch Dielectric Coating Mirror
Offered Coating Ultraviolet, visible and infrared Fused Silica Broadband Dielectric Mirrors
The mirror is one of the most important optical elements in the laser system and is a key part of the resonator in the laser transmission
The process has an irreplaceable role.
Many thin film spectra are based on the initial structure of the reflective film
Design, laser film is no exception.
Map optics provides low scattering, low absorption, and ultra high laser damage
Threshold, each performance index reaches the international leading level of reflective film element, working wavelength range coverage
248nm~3000nm, the maximum size of the element can be up to meter level, the damage threshold of small diameter element is greater than
60J/cm2 (1064nm,3ns), the damage threshold of large-diameter components is greater than 30J/cm2 (1064nm)
, 3 ns).
In general, optical systems in order to ensure good beam propagation characteristics, for the film
Elements, in addition to the spectrum requirements, damage threshold requirements, but also need to have a good surface shape coated elements
Precision.
Through closed-loop control process, the surface shape variation of thin film elements can be effectively suppressed in the thin film
Accumulated rich experience in stress control, for φ 150mm diameter and below components, reflective surface shape fine
The degree can be controlled in λ/10 (λ=632.8nm), for φ 400mm caliber components, reflective surface shape
Can be controlled at λ/4 (λ=632.8nm).
Fused Silica Broadband Dielectric Mirrors offer excellent reflectance over four different spectral ranges. Due to run-to-run coating variations, please note that the specified spectral range listed for each coating is smaller than the actual spectral region over which the mirror is effective.
