Short wave pass filter

To meet the needs of sensing chips such as CCD or CMOS, allowing maximum visible light penetration, cutoff or reflection in the anti infrared region, or transmission or cutoff in any wavelength band, it is necessary to ensure excellent flatness and high transmittance in the short wave region, which is higher than the difficulty coefficient of long wave pass filters. Especially in the field of ultraviolet light sources, it is not particularly easy to achieve products that allow ultraviolet light to pass through as much as possible and allow visible and near-infrared reflection or cutoff.

Commonly used in ultraviolet light sources, mobile phone cameras, laser protection, thermal reflection lighting systems, and fluorescent ink laser imaging.
