Sample Door

The sample door can be opened for a completely unobstructed view of the sample presented at

the view port. When completely open, the sample door allows you to adjust the sample at the

view port for optimal placement.

To use the sample door:

1. Open the sample holder by pulling it towards you. Place your sample at the view port and

close the sample holder.

2. Open the door from the top by using your fingers, and gently lower the door to the complete

open position. See the figure below.

3. With the sample door completely open, view the sample at the view port and make sure the

sample is in an optimal position for measuring.

4. Close the sample door and prepare for the measurement.

Specular Control

You can change the specular component setting on the spectrophotometer for reflectance

measurements using your software application. Select the desired specular component

measurement mode; Included (SCI), Excluded (SCE), or Dual Mode (SCE/SCI). The indicator for

either setting (or both if you have dual mode) on the front panel becomes illuminated based on

your selection. The instrument simultaneously measures specular included and specular excluded

for all reflectance measurements. Your software application should decide which measurement

data to request from the spectrophotometer according to the user requirements.

UV Control

Your spectrophotometer is equipped with an automated 400nm UV filter. This can be set to fully

exclude the UV portion of the light source in the spectrophotometer or can be used to calibrate and

adjust the UV level, for instance to match the UV component of D65 daylight. The instrument

supports built-in UV calibration positions for UV included, UV excluded, and D65. The instrument

also supports an unlimited number of user-defined UV positions which are set up, calibrated, and

managed using the PC software application. A UV calibration plaque is provided in the accessory

drawer that has been calibrated in the factory with a CIE whiteness value for true D65. Your system

includes a 400 nm UV filter, and may optionally include a 420 and/or 460 nm UV filter as well.

Aperture Control

By default, the spectrophotometer is configured to auto-recognize an aperture plate when

installed at the measurement port, and to auto-drive the lens to the matching size. The lens

position is also dependant on the measurement mode. If for example the instrument is configured

with the 10 mm aperture plate in a reflectance measurement mode and the user switches to a

transmission measurement mode, the instrument auto-drives the lens to create the measurement

size at the transmission measurement location.

Note: The automatic lens behavior can be overridden by the user in software if desired. If you prefer to

not have matching aperture and lens settings (to have an over illumination setup), you can use your

software application to configure the instrument. Keep in mind that a valid measurement size is less than

or equal to the aperture plate size. If the lens position and the installed aperture plate do not match, the

lens LED will illuminate red to indicate this discrepancy. Auto recognition is applicable to Reflectance

mode only.

To install an aperture plate on the instrument:

1. Open the sample holder to the fully open position.

2. Using your fingers, remove the aperture by lifting outward from the notch below the existing

aperture plate.

3. Locate the plate to be installed in the accessory drawer and fit the aperture over the rim on

the sample door. The plate is held in place by magnets.

4. Gently close the sample holder.

5. The aperture plate will be automatically recognized when the door is closed, and activate the

auto-zoom lens if set to the auto mode. Auto recognition is only valid for Reflectance mode

aperture plates. For transmission aperture plates, the asterisk LED lights up green.

CALIBRATING

The spectrophotometer should be calibrated every eight hours of operation.

Each spectrophotometer configuration that is used should be calibrated. A configuration consists

of the following components:

•Measurement mode: Transmission, Reflectance, R/T, or Haze

•Aperture size (3.5 mm, 6 mm, 10 mm, 17 mm, or 25 mm)

•Lens position

•Specular included or excluded condition (SCI or SCE)

•UV included, D65 calibration or excluded condition

Calibration Notes

•Dirt or dust in the optics area will cause an inaccurate calibration reading. Refer to

the Appendices for optics cleaning procedure.

•The white calibration tile is dramatically affected by smudge marks, dust, and

finger prints. Refer to Appendices for calibration tile cleaning procedures.

•The black trap should be cleaned periodically to remove any dust or

contamination. Refer to Appendices for black trap cleaning procedures.

Reflectance Calibration Procedure

To calibrate your spectrophotometer in reflectance measurement mode you need to use your

software application. Follow these steps:

1. Verify the 25 mm aperture plate is installed.

2. Launch the calibration procedure from the software application.

3. Remove the white calibration tile from the accessory drawer. Pull down on the sample holder

and position the tile on the sample holder clamp. Make sure the white ceramic side is facing

the aperture plate.

4. While holding the tile in place, close the sample holder to the aperture plate.

5. Initiate the calibration tile measurement from the software. After the measurement, remove

the calibration tile and return it to the accessory drawer.
