DH-2000-CAL Deuterium Tungsten Halogen Calibration Standard

The DH-2000-CAL Deuterium Tungsten Halogen Calibration Standard is a UV-NIR light source used to calibrate the absolute spectral response of a radiometric system. With the DH-2000-CAL and SpectraSuite Software, you can determine known absolute intensity values at wavelengths from 220-1050 nm.

The DH-2000-CAL is specifically calibrated for use with optical fibers or a cosine corrector; the calibration data includes absolute intensities for wavelengths between 220-1050 nm at the fiber entrance port for both a bare fiber and a CC-3-UV Cosine Corrector.

Features

  • UV-NIR Calibration Source. For use in performing fast, radiometric calibrations from 220-1050 nm

  • NIST-traceable Calibration from 220-1050 nm. Provides absolute spectral intensity in µW/cm2/nm at the fiber port

  • Calibration Certificate. Calibration data is provided in paper and electronic formats for use with SpectraSuite Software

Included with the Lamp

The DH-2000-CAL comes with the CC-3-UV Cosine Corrector. Also included is a calibration certificate and a diskette with a data file for use with our SpectraSuite Software.

Other Calibration Services

The DH-2000-CAL typically provides about 50 hours of operation before recalibration is necessary. We recalibrate these lamps in-house. (For more information on the DH-2000-RECAL, contact an Applications Scientist.) Also, by using our SPEC-CAL-UV in-house calibration service, it is possible to have your UV spectrometer radiometrically calibrated without purchasing a DH-2000-CAL. The calibration is good for about one year, provided the optical fiber is not removed from the setup, as the system is calibrated specifically for use with a fiber.

User's Tip

Radiometric Calibration Sources are not illumination sources for spectroscopic measurements. For illumination, use the DH-2000.

DH-2000-CAL Spectral Output

HL-2000 Spectral Output

These spectral output graphs were taken separately for the deuterium (200-400 nm) and the tungsten halogen bulbs (400-1100 nm) to avoid a sharp line spectrum >400 nm in the deuterium trace.
