High Quality 334.1nm UV Narrow Bandpass Filter For Mercury lamp
334.1nm narrow bandpass filter is UV filter.
UV filters are widely used in chemical analyzer, anti-counterfeiting, and has the characteristics of high technology content and good color concealment. Long-wave fluorescent anti-counterfeiting technology is an advanced anti-counterfeiting technology currently used in bills and currency. Short-wave anti-counterfeiting technology uses special equipment for identification, so it has stronger anti-counterfeiting and concealment performance. In order to identify the printing quality of fluorescent characters, fluorescent watermarks, fluorescent two-dimensional codes, fluorescent logos, etc., machine vision is usually used for detection, and it can also be used in medical equipment and ultraviolet fluorescent endoscopy applications.
334.1nm narrow bandpass filter main use for mercury lamp.
