General Description
The 938 measures spectral reflectance from 400nm to 700nm in 20nmintervals.
It has a 0° illumination angle, a 45°viewing angle, and features adual-beam, single light pulse compensation method to insure accuracy. The 938 calculates colorimetric, densitometric, and spectrophotometric data.
The 938 displays colorimetric & densitometric data, and can output (to aprinter or computer) colorimetric, densitometric, and spectral data. An optionalsoftware package (e.g., SpectroStart) can collect, sort, view and analyzeL*a*b*, L*C*h°, and spectral data using an IBM compatible computer.
Colorimetric Features:
The 938 measures spectral reflectance, absolute color or colordifference, and absolute index
or index difference for Whiteness and Yellowness.

There are eight different CIE Illuminants for calculations under varyinglighting conditions.
In addition, you can select the CIE 1931 2° Observeror the CIE 1964 10° Observer.

Twenty four different reference values (Ref 01 - Ref 24) can be enteredinto the unit manually (numerically) or by measuring a reference sample.
The exceptions are that the reference values for Whiteness andYellowness can only be entered by measurement.
During reference entryall color spaces are automatically updated when a change has been made inone of them.
