2. Position the sphere cap with the 'S' mark up.

3. Click the Baseline button in the Scan dialog box. Follow the on-screen

prompts to perform a 100%T baseline scan and a 0%T baseline scan.

Hot Tip

When performing specular zero (%T) collect, remove the reference PTFE disc

and allow the light to be trapped by the external sample compartment.

4. Once the baseline correction is complete, the Ordinate status display in the top

left corner of the dialog box will show 'Zero baseline' in red text.

5. Clamp the sample over the reflectance port. The sample should be

homogeneous, substantially flat, and large enough to completely cover the

image.

6. Click the Start button to perform the scan of the total (specular and diffuse)

reflectance of the sample.

7. Turn the sphere cap so the 'D' mark is up, and click the Start button to collect

the diffuse-only data.

8. From the main Scan window, click the Calculator icon

to open the open

the Maths dialog box.

9. On the graph displayed, highlight the first scan (of the total reflectance) by

clicking on it. When the scan is selected, it will be highlighted in red.

10. From the Maths dialog box choose Selected Trace and then the '-' (minus)

sign.

11. On the graph displayed, highlight the second scan (of the diffuse-only

reflectance), by clicking on it. When the scan is selected, it will be highlighted

in red.
