Attaching the Transmittance Zero Calibration Plate
The Transmittance Zero Calibration Plate is used for performing zero calibration for transmittance measurements.
○ Before starting transmittance calibration and measurements, attach the LAV (ø25.4 mm) target mask and
○
position the white calibration plate at the reflectance measuring port.
○ Before starting transmittance calibration and
○
measurements, set the measurement area to LAV and
the specular component to SCI using the software.
○ Before starting transmittance calibration and
○
measurements, set the same UV light quantity as
when performing measurements using the software.
In the fluorescent measurement that does not
require rigorous accuracy (that does not perform
fluorescent calibration), perform measurement
under the condition that the UV cut-off filter does not
cover the xenon lamp (UV light quantity is 99.9).
Procedure
1.
Open the cover of the transmittance chamber.
2.
Position the Transmittance Zero Calibration
Plate in the transmittance chamber so that it
completely blocks the illumination window.
Memo • When using the optional Transmittance Specimen
Holder, position the Transmittance Zero Calibration
Plate in the holder. For information on installing
the optional Transmittance Specimen Holder,
refer to the instructions included with it.
3.
Close the cover of the transmittance chamber.

Notes on Use of Transmittance Zero Calibration Plate

○ Take care not to scratch, touch, or make the surface of the transmittance zero calibration plate dirty with
○
such as fingerprints.
○ If the transmittance zero calibration plate gets dirty, wipe it with a soft, clean, dry cloth.
○
○ If dirt is difficult to remove, dampen a cloth with commercially available lens cleaning liquid and wipe the zero
○
calibration plate. Then wipe off the liquid with a cloth dampened with water, and leave the plate to dry.
○ Should the transmittance zero calibration plate get so dirty that it cannot be cleaned, replace the plate
○
with a new one.
