Features

  • Fast, Easy Data Acquisition
  • Wide Spectral Range
  • 2 nm Spectral Resolution
  • Wavelength Accuracy <0.5 nm
  • TE-Cooled Detector Option
  • Fiber Optic Input Cable for Remote Operation

Labsphere DAS Diode Array Spectrometers are multi-channel analyzers designed for real-time spectral analysis. Spectral analysis provides useful information on the color characteristics of numerous materials and light sources. Spectral analysis techniques that use diode array technology are widely used in analyzing lamps and LEDs and in quantifying the reflectance, transmittance, color and haze of many materials. The DAS Diode Array Spectrometers are available in two models to accommodate specific application needs. The instruments offer high sensitivity, low noise and broad spectral response. An integral fiber optic cable connects the spectrometers to the light source being measured. The cable offers added flexibility for remote positioning of the spectrometer. The spectrometers are packaged in self-contained compact enclosures that are easily connected to a PC via a serial port.

DAS-1100 Diode Array Spectrometer
for applications in the 390-760 nm wavelength range

The DAS-1100 Diode Array Spectrometer features a single concave holographic grating and a 1024 element array. The spectrometer covers the spectral range from 390 to 760 nm. The DAS-1100 spectrometer features a thermoelectrically cooled photodiode detector to provide signal stability and reduce the detector dark current for longer integration time in low signal level measurements.
DAS-2100 Diode Array Spectrometer
for applications in the 350-1050 nm wavelength range
The DAS-2100 Diode Array Spectrometer offers an extraordinary combination of spectral range, spectral resolution and order sorting. A novel design approach provides both wide spectral coverage and narrow spectral resolution. The spectrometer uses two diffraction gratings and two 1024 element arrays to cover a wide spectral range extending from 350 nm to 1050 nm. This design avoids the overlapping of spectral orders. Special data acquisition software combines the array signals into a single spectrum. The DAS-2100 spectrometer features a thermoelectrically cooled photodiode detector to provide signal stability and reduce the detector dark current for longer integration time in low signal level measurements.
