JETI Specbos 1211UV2- Color Brightness Meter - Spectral Color Brightness Meter

Product Description:

JETI Specbos 1211UV2- Color Brightness Meter - Spectral Color Brightness Meter is a portable broadband miniaturized spectral radiometer that extends the original wavelength of the device in the ultraviolet range to 230nm, used for measuring spectral radiance and spectral irradiance in the wavelength range of 230-1000nm. According to the IES 62471 standard, this extension makes specbos 1211UV-2 suitable for hazard measurement. Other applications include the measurement of ultraviolet exposure instruments, tanning rooms, etc. In addition, all other parameters of Specbos 1211UV-2 are the same as those of the standard equipment Specbos 1211-2, including sensitivity, viewing angle in radiation mode (1.8 °), and optical resolution. This spectrometer is based on NIST traceable calibration and can switch between irradiance and radiance modes to meet different measurement needs. It is based on a high-quality array spectrometer with controlled characteristics, featuring high sensitivity, fast and accurate measurement, lightweight and easy to carry. Starting measurement through an external trigger signal, with a built-in target laser that can be used for rapid alignment; In addition, it also supports multiple interfaces:

JETI offers two models of spectral radiometers: spectrorval and specbos. These two types of spectral radiometers are based on high-quality array spectrometers with controlled characteristics. This spectrometer uses a detector array instead of a single detector, so only fixed components are required. All calibrations can be traced back to NIST. This array spectrometer consists of input slits, gratings, possibly other optical imaging elements, line detectors, and a stable housing. Its development also overcomes some drawbacks, such as non parallel measurement, movable components, and size of occupied space. They are widely used in PC coupling, standalone, and handheld devices, and even in line process measurement.
