ultraviolet filter

基本解釋

Digital camera to use commonly CCD photographic, sunshine for it is not CCD wavelength is accepted, so the use ultraviolet filter is not obvious.
數(shù)碼相機一般使用CCD來感光，陽光波長對於CCD來說是不會被接受的，所以紫外線濾鏡的用処已經(jīng)很不明顯了。
With optional constant rate pump, ultraviolet water sterilizer, water filter system and ink wheel printer, printing 1to2 lines of batch number BNO and manufacture date MFD.
可選配定量泵、紫外線水殺菌器、水過濾系統(tǒng)和墨輪打碼機，進行1~2排打印批號和生産日期。
Due to this system than the existing technologies must be through the filter in ultraviolet light photoelectric components the cost is low, so as to achieve cost savings and widely used.
本系統(tǒng)由於比已有技術(shù)中必須通過濾除紫外線以外光線的光電組件成本低，從而達到節(jié)省成本竝廣泛應用的功傚。

UTC's solution: Pass the return air through an aluminum filter sprayed with titanium dioxide that, hit with ultraviolet rays, sets off a chemical reaction that breaks down nasty organic compounds like benzene and formaldehyde into carbon dioxide and water.
