Pengukur Transmisi Spektrum LS182

LS182 spectrum transmission meter is a device that can test the SHGC value (that is, the total solar transmittance, also called the solar heat gain coefficient), 940nm, 1400nm, TSER and Full IR rejection rate, 365nm ultraviolet rejection rate and 380nm-760nm visible light transmittance. The testing principle of the LS182 spectrum transmission meter is to use an ultraviolet light source, a visible light source and an infrared light source to illuminate the measured transparent materials. The sensor detects the incident light intensity of the light source and the light intensity passing through the materials. The ratio is equals to light transmittance which is shown in percentage. For most solar films, the visible light is marked with the transmittance index and the infrared and ultraviolet rays are marked with the rejection rate index.

The rejection rate = 100% – transmittance

Application

The LS182 spectrum transmission meter has a wide range of applications. Due to its parallel light path and wide test slot, it can be used in the solar film industry to test solar films, laminated glass, etc., as well as various large thickness materials. The instrument is suitable for using on solar film performance exhibition, production, quality inspection, inspection and other occasions.
