Information about: "How to Use the 2DMPP spectrograph for Light and Irradiance Measurements



Characteristics of the spectrometer applications for light measurement
  • optical resolution of about 1nm FWHM (1024 pixel, range 380 - 880nm)
  • 16 Bit- A/D converter, high SNR of the whole system
  • Integration time from 8ms to 160sec
  • highest wavelength stability
  • cooled detector offering high long term stability
  • no mechanically moving parts
  • software with all common parameters for light measurement
  • calibration storage in the internal EEPROM



CDI2DMPP - short presentation
The CDI2DMPP described in the product section is a very interesting alternative for applications in light measurement. The heart of this compact system is the TE cooled Si-CCD array with 1024 x 64 elements. The detector has a very high signal-to-noise ratio. The compact spectrometer optics is directrly connected to the detector. This offers very high long term stability. Recalibration of the wavelength axis is not necessary.

The picture below shows the spectrometer with attached fiber optics and the data transmission cable that allows the connection of the system with any PC, industrial PC or notebook.


Spectrometer options
  • Versions with higher optical resolution
  • special wavelength ranges
  • UV versions
  • complete systems with integrating sphere or diffusor


Applications in light measurement
  • high-pressure lamps / discharging lamps
  • fluorescent tubes, line emitters of any kind
  • LED
  • LCD displays
  • monitors
