Appendix
To customers who execute micro-spectrophotometry by placing a sample on the tilt stage
It is recommended to adjust the tilt of the tilt stage vertically to the optical axis when the
customer who purchased a transmit unit and 45-degree expansion unit performs
micro-spectrophotometry. For the customer who measures a thin plate, especially, be sure
to perform this adjustment.
[Tilt adjustment of the tilt stage]
(1) See
“
3.7 Device connection
”
in the instruction manual for the NIR
Micro-spectrophotometer USPM-W-B
for installation.
(2) See
“
4.2 Start-up
”
in the instruction manual for the NIR
Micro-spectrophotometer USPM-W-B

(3) Set a revolver.
The revolver is adjusted to the through position (in which an objective lens is not
installed).
(4) Install a BK7 reference sample in the tilt stage.
(5) Adjust the tilt of two axes to the optical axis using the tilt stage adjustment knob.
[Tilt adjustment]
Make adjustment using the tilt adjustment knobs so that outgoing beams are parallel to the
optical axis while confirming a FOCUS window. Adjust such so that the (X:*** Y:***) value
displayed in the lower-left position of the FOCUS window is the minimum. It is
recommended that you set the value to (X:0±1 Y:0±1) when performing more accurate
measurement.
