Measurement of optical transmissivity at high temperatures

12.07.2016
Scientists at Laboratory of measurement of optical properties have developed new system for measurement of specular optical transmissivity at high temperatures. The system uses a laser, laser power meter, cylindrical furnace, thermocouple measurement and infrared camera. Temperature range is from room temperature up to 700°C. This system was used for transmissivity measurement of optical glass for Preciosa Ornela a.s. industrial company at temperatures up to 600°C.
