Transmittance Measurement - Konica Minolta CM-36dGV Instruction Manual

 Transmittance Measurement
• When using the optional SpectraMagic NX, set the measurement
method to transmittance in advance.
• Install the target mask for LAV measurement and the white
calibration plate onto the instrument.
Procedure
1 Open the transmittance specimen chamber cover.
2 Place the specimen in close contact with the illumination
window side.
• Set the specimen so that the part that will be measured
completely covers the illumination window.
Memo
• Although the specimen can be set on either the illumination
window side or receptor window side, it should be set on the
illumination window side for ordinary use. In this case, the
illumination/viewing system uses diffuse illumination and 0°
viewing (di: 0°, de: 0°).
When the specimen is set on the receptor window side, the
measurement type is approximately 0°:0°. Although this does
not completely match the definition in JIS Z 8722 or other
standards, it can be used as a relative value for management.
• For setting specimens that are difficult to hold or specimens
with the designated thickness, use of the optional
transmittance specimen holder CM-A96 is recommended.
For information about installing the transmittance specimen
holder, refer to the instruction manual that was provided with
the transmittance specimen holder.
