UVA Ultraviolet Analyzer (UV Analyzer) Fluorescence analysis principle

The analyzer uses low pressure mercury vapor discharge, low pressure mercury lamp is mainly emitted by 254nm short-wave ultraviolet light using light quantum modulation method, the inner wall of the lamp is coated with a layer of characteristic fluorescence material, so that it can absorb 254nm short-wave ultraviolet light and form a wide ultraviolet spectrum band in the edge of 365nm, so that it has low pressure mercury lamp power consumption is small, with off with open, With the characteristics of open use, through the filter color filter to filter the visible light, get high energy long wave ultraviolet.
