BIX-8805 series Spectroradiometer with NIST calibrated
  • Details


Radiometry is a science that studies the measurement of electromagnetic radiation energy, applicable to the entire electromagnetic waveband. Irradiance is defined as the power per unit area when electromagnetic radiation is incident on a curved surface. It is intuitively understood as the quantified value ofenergy at the point of incidence. The physical unit is watts per square meter (W/m^2). The irradiance measurement kit consists of a spectrometer, optical fiber, cosine corrector, and holder. The spectrometer is connected to a cosine corrector with a known surface area through an optical fiber. The entire system is calibrated by the NIST traceable standard light source, which can achieve UVA, UVB, UVC and other wavelengths of ultraviolet intensity detection, as well as irradiance in a specific band, accurate measurement of a series of parameters such as radiation flux and radiation intensity. The device is simple to test and easy to use,   and can be widely used in research fields such as ultraviolet disinfection lamps, ultraviolet fluorescent lamp irradiation intensity measurement, and LED light radiation safety measurement.
