Economical Shortpass Filter, Φ12.5mm, Transmission Wavelength: 485~1000nm, Blocking Band: 1130~1370nm, United Optical Technology Co., Ltd (CAT#: STEM-OP-3907-YJL)

Economical Shortpass Filter, Φ12.5mm, Transmission Wavelength: 485~1000nm, Blocking Band: 1130~1370nm, model 218600, is manufactured by United Optical Technology Co., Ltd.
The Economical Shortpass Filter allows light with a wavelength smaller than the set wavelength to pass through and cuts off light with a wavelength larger than the set wavelength.
If the surface of the shortwave filter is dirty, use dust-free lens cleaning paper dipped in alcohol to wipe the lens surface. Do not wipe with cloth or paper with a very rough surface or water, otherwise the surface of the shortwave filter will be damaged.
