5. Remove the sample from the sample holder clip and load the empty sample holder

into the centre-mount port.

6. Load Spectralon reflectance standards at the reference and sample reflectance ports.

Install the magnetic covers over each respective port.

7. Collect a Baseline scan

8. Mount the sample into the centre-mount sample holder and load the assembly into the

integrating sphere.

9. Click the Setup button and check the parameters. Normally, the setup parameters for

the application should match those used for the baseline scan. If using a previously

defined baseline correction, retrieve the correct baseline.

10. Click the Start button.

The value displayed by the instrument is the absolute sample reflectance. No data

correction is required.

Jaw Style Sample Holder Measurements

1. Darken the room and drive the instrument to 500 nm

2. Mount the sample onto the sample holder, making sure it is properly centreed and

secured to the holding jaws. Load the assembly into the integrating sphere and set the

anticipated angle of incidence using the attached dial.

3. While viewing the sample surface through the reference port, check that the sample

beam strikes the centre and does not overfill the sample at the angle selected. This step

may require use of a piece of translucent paper and will be more difficult at greater angles

of incidence. If the beam is off centre or will not fit on the sample, either adjust the

sample mounting in the sample holder or readjust the sample beam optics to achieve the

correct alignment. If any adjustments are made to the optics, make sure the sample beam

does not clip the transmission port.
