ORPHEUS User’s Manual

Light Conversion
To apply an offset:
1.
Reset motor positions.
2.
Switch to “Advanced user level” in WinTOPAS application using the menu “Tools” →
“Access
level”. The password for advanced user level is “1600”
.
3.
Set 680 nm as an output from the ORPHEUS.
4.
“Calibration”
→
“Optical” →
“OPA”
→
“SIG”
and select the motor (for which you want to apply an
offset) on the left side of the window to gain access to the calibration curve.
5.
For the same motor, select the motor control section on the right side of the window.
6.
Adjust the position of the selected motor monitoring OPRHEUS output: spectrum and/or pulse
width.
7.
Press “Set Offset”
.
8.
Repeat steps 4-6 for other motors you want to apply an offset.
The offsets for each motor are stored in calibration configuration. The settings of each calibration
point remain unchanged. The logic of setting the wavelength with and offset is the following:
1.
Lookup for the motor position from the calibration curve.
2.
Interpolate the position if in-between wavelength is entered.
3.
Add/subtract each motor position by the offset.
If the offset is re-zeroed
–
the position of each motor will be the same as the original calibration
unless “Shift curve to make offset zero” was pressed after setting the offset. This function adds or subtracts
offset value from the current tuning curve and makes the offset permanent. Visit WinTopas4 info page for
more information.
