Product Name: Instrument Systems CAS 140 Array SpectroradiometerPurpose: It is used for precise infrared radiation measurement. It is suitable for the research, development and quality control of high - end LEDs, luminaires and displays, and is also often used in work related to broadband light sources and infrared LEDs. When combined with other models, it can achieve complex spectral measurements over an extremely wide wavelength range.Technical Principle: It decomposes light into components of different wavelengths through spectroscopy technology, uses a detector to sense the intensity of light at each wavelength, and then converts it into spectral data through a data processing system to analyze the characteristics of light.Performance: There are different models. For example, the wavelength range of IR1 is 780nm - 1700nm, and that of IR2 is 1500nm - 2150nm. The detector can be cooled to - 10°C (IR1) or - 20°C (IR2) to reduce dark current. It is equipped with a spectrograph with excellent stray light suppression and an integral density filter wheel, and is equipped with the feature - rich SpecWin Pro spectral software. It has high measurement accuracy, and the calibration can be traced back to PTB or NIST.
