Feature Summary
The Dataflash is one of a family of Datacolor instruments that employs state-of-the-art
features including the spectrometer, light source, and optics. Below is a summary of those
features:
FEATURE DESCRIPTION PURPOSE/BENEFIT
Instrument Type Dual-beam
spectrophotometer with
xenon flash lamp Industry standard.
Measurement
Geometry 45º illumination
0º viewing Results provide good
agreement with visual
evaluations of sample color.
SP2000 Spectral
Analyzer Proprietary dual-channel
holographic grating. 256-
photodiode linear arrays
used for both the
reference and sample
channels. Dual channel design provides
continuous monitoring of sample
illumination and compensates
for changes. 256-photodiode
array enhances the precision of
the measurement.
Light source Pulsed xenon flash lamp Does not require warm up
Effective
Bandwidth 10nm Greater precision enhances the
measurement accuracy.
