A type of filter, the feature of related spectrum involves minimizing the transmission in IR and UV bands.
May be applied in various optical systems, the effect involves filtering IR and UV of light source to achieve the protective purpose for optical systems.
What We Achieved :
|Material||Glass, Borofloat, or equivalent|
|Thickness||0.7, 1.1 mm, and others|
|Spectrum||T abs. < 1% up to 390 nm; |
T = 50% for λ = 410 ± 5 nm;
T avg. > 95% for λ = 420– 680 nm (UV/IR-Blocker);
T avg. > 95% for λ = 420– 760 nm (UV-Blocker);
T = 50% for λ = 710 ± 10 nm (UV/IR-Blocker);
T avg. < 5% for λ = 750–1100 nm (UV/IR-Blocker);
|Temperature Resistance||< 400°C|
|Remark||* In-house glass polishing |
* Robust Ag metal and dielectric surface coating
