Reflectance measurement

○ Make sure that there is nothing in the transmittance chamber.
○ Before starting reflectance measurements, attach the target mask to be used for measurements.
○ Before starting reflectance measurements, set the measurement area, specular component, and UV light
quantity using the software.
Procedure
1.
Pull the sample holder toward
you and keep it open.
○ The sample holder will remain open when
it is opened more than 70 degrees.
2.
Secure the specimen with the sample holder.
3.
Open the viewfinder cover and
check the measuring point.
Memo • When checking the measuring point while you are
seated, position the viewfinder cover at the desired
angle so that the image reflected in the mirror
inside the viewfinder cover can be observed .
• When the viewfinder cover is opened, the
specimen will be illuminated for 60 seconds by a
lamp to enable you to check the measuring point.
○ Do not exert excessive force on the
viewfinder cover while it is open.
○ It is not possible to perform measurement
if the viewfinder cover is open.
4.
Adjust the position of the specimen
so that the area to be measured is
centered in the measurement aperture
and then close the viewfinder cover.
○ When adjusting the position of the specimen, the
sample holder must be pulled and kept open. This
will prevent the sample holder from scratching
the surface of the specimen during adjustment.
