The meter combines three measuring light paths into one. Users can select to measure the transmission rate or rejection rate. Four display interfaces can be switched. The LS108 spectrum transmission meter uses a 395nm purple light source, a 430nm blue light source and a visible light source to illuminate the transparent material during test. The sensor detects incident light intensity of the three light sources and the light intensity after passing through the transparent material. The ratio of transmitted light intensity to incident light intensity is transmittance, displayed as a percentage.\u003c\/span\u003e\u003cspan\u003e \u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cspan\u003eRejection rate=100%- transmission rate\u003c\/span\u003e\u003c\/p\u003e\n\u003cdiv\u003e\n\u003ctable\u003e\n\u003cthead\u003e\n\u003ctr\u003e\n\u003cth\u003e\u003cspan\u003eParameter\u003c\/span\u003e\u003c\/th\u003e\n\u003cth\u003e\u003cspan\u003eLS108 Spectrum Transmission Meter\u003c\/span\u003e\u003c\/th\u003e\n\u003c\/tr\u003e\n\u003c\/thead\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cspan\u003ePurple light peak wavelength\u003c\/span\u003e\u003c\/td\u003e\n\u003ctd\u003e\u003cspan\u003e395nm\u003c\/span\u003e\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cspan\u003eBlue light peak wavelength\u003c\/span\u003e\u003c\/td\u003e\n\u003ctd\u003e\u003cspan\u003e430nm\u003c\/span\u003e\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cspan\u003eVisible light\u003c\/span\u003e\u003c\/td\u003e\n\u003ctd\u003e\u003cspan\u003e380nm-760nm full wavelength, in line with CIE photopic luminosity function\u003c\/span\u003e\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cspan\u003eMinimum test sample size\u003c\/span\u003e\u003c\/td\u003e\n\u003ctd\u003e\u003cspan\u003e1mm\u003c\/span\u003e\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cspan\u003eResolution\u003c\/span\u003e\u003c\/td\u003e\n\u003ctd\u003e\u003cspan\u003e0.1%\u003c\/span\u003e\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cspan\u003eAccuracy\u003c\/span\u003e\u003c\/td\u003e\n\u003ctd\u003e\u003cspan\u003e±2% (colorless uniform transparent material, 0-90% transmittance)\u003c\/span\u003e\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cspan\u003eWeight\u003c\/span\u003e\u003c\/td\u003e\n\u003ctd\u003e\u003cspan\u003eabout 1570g\u003c\/span\u003e\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cspan\u003eDimension\u003c\/span\u003e\u003c\/td\u003e\n\u003ctd\u003e\u003cspan\u003e170mm × 180mm × 144mm(L*H*W)\u003c\/span\u003e\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cspan\u003eDisplay\u003c\/span\u003e\u003c\/td\u003e\n\u003ctd\u003e\u003cspan\u003e480px * 272px color LCD\u003c\/span\u003e\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cspan\u003ePower supply\u003c\/span\u003e\u003c\/td\u003e\n\u003ctd\u003e\u003cspan\u003eDC5V\/1A\u003c\/span\u003e\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\n\u003c\/div\u003e\n\u003cp\u003e\u003cspan\u003e\u003cstrong\u003eFeatures:\u003c\/strong\u003e\u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cspan\u003eThe spectrum transmission meter has a wide range of applications, suitable for the transmission and rejection rate test of glasses, glass, anti-blue light materials, mobile phone lenses, etc.\u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cspan\u003eThe light transmission meter can simultaneously measure the transmission value and rejection rate of 430nm blue light \/395nm purple light \/380nm-760nm visible light and UV400 (the maximum ultraviolet rejection wavelength).\u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cspan\u003eThe meter uses one light path.
