Note
This section now provides information on how to enter only some of the
key measurement settings - for complete details on all settings, see Meas-
urement settings reference later in this chapter.
2. Choose the Sample-Identification settings to record both the Sample
Name details and define any further information fields (for example, Notes)
that will help users to repeat the measurement at a later date.
3. Use the Sample-Material section to define the optical properties (the
Refractive index and Absorption index) of the new material. The material
may already be stored in the system’s Materials database. Check this first by
clicking Browse database - select the material if it is present to automatically
add the RI and Absorption values to the measurement.
4. Use the Measurement-Duration section, shown below, to set up measure-
ment times for the red and blue measurements.
