UV Cut-off Filter
A filter that cut off ultraviolet rays (UV) and transmits visible light.
The transmittance and reflectance can be adjusted for each wavelength according to the usage environment.
1. High durability, shiftless (non-shift) film due to dielectric multilayer film
2. Adjustable transmittance and reflectance at wavelengths of 200 nm and above
3. Depending on the wavelength, it is possible to cut by absorption and reflection
・ Suppression of deterioration of optical elements due to UV irradiation from a mercury lamp light source
・ Selectively cut UV-B and UV-C, which have a large effect on the human body
