UV Longpass Filters ZJB Series
Our products UV longpass Filters ZJB Series are colorless filter galss with an ultraviolet transmission, they are equivalent to longpass filters WG series of Germany Schott and optical filter UV Series of Japan Hoya.
UV longpass filter glass cut off the wavelength light shorter than a specific wavelength as much as possible, while transmitting the longer wavelength light as much as possible, within UV wavelength range. Their typical applications include fluorescent spectroscopy systems, medical equipments. Additionally, they are commonly used in conjunction with shortpass filters for bandpass filtration applications.
