3. AvaSoft manual for FOS-2-INL
3.1 General
AvaSoft 8 operates the FOS-2-INL as a separate device.
Please refer to the AvaSoft manual for general operation of the spectrometer.
This manual only describes the changes that are relevant to the FOS-2-INL.
These are mainly situated in the Options menu and in the Spectrometer panel in the main
menu.
To begin, set-up the FOS-2-INL in the Options screen.
Select ‘Options’, ‘Electronic Optical Accessories’
If the device is not listed yet (the default name is ‘BMSFOS000’), press the ‘Add’ button and
select ‘Beam Splitter / FOS’ in the “Select Device Type’ drop down box.

Press ‘OK’
If you press ‘Del’, and close the dialog box, the FOS-2-INL will not be used.
After pressing ‘Add’ in the initial setup, you will get the screen above.
Select a spectrometer to connect to the FOS-2-INL.
To enable the shutter on Save Dark, check the box ‘Enable’.
You can edit the Channel names in the respective edit boxes.
The Switch Settings allow you to either manually change channels, or change them with a timer.
You can set the timer interval in seconds in the respective box.
Press ‘OK’ to close the dialog box, and continue using AvaSoft.

Now you are able to use the accessory as FOS-2-INL in combination with the selected spectrometer
and start measuring spectra.
Spectrometer Panel:
Click the icon to change the settings of the spectrometer that is used. Please refer to the
AvaSoft 8 manual for a detailed description of all options.
The icon will take you to the same settings that are available after opening the ‘Options’,
‘Electronic Optical Accessories’. Please refer to the description above.
You are now ready to take readings.

3.2 Sequencer
Click the icon to change the settings of the sequencer that can be used.
Click the ‘Add Step’ button to add a step to the sequencer.
You can change the position, settle time, minimal time and number of measurements.
When the position gets changed the measurement will starts after the ‘settle time’ has expired.
This means that the ‘settle time’ represent a delay time that is necessary for the mechanical
movement. The ‘settle time’ can be reduced.

After the ‘settle time’ the ‘minimal time’ will be used.
The ‘minimal time’ represents the minimum time of the measurement at the position that is set. If
the total amount of measurements will take more time than the ‘minimal time’ this will be
overruled.
The ‘Current Channel’ drop down box lets you change channels manually. If you have selected timer
operation in the ‘Options’ dialog box, it will be dimmed.
When operating in timer mode, the time to the next switch will be displayed in the next line.
3.3 Correction for drift:
The combination of FOS-2-INL and spectrometer can also be used for correction for drift
You can use the second channel to correct the first channel for drift, e.g. resulting from slow
deterioration of the lamp intensity.
First you have to set-up the accessory as FOS-2-INL as described above.
Select ‘Options’, ‘Correct for Drift Channel’
Select the channel in the ‘Correction Source (reference)’ drop down box that you want to use to
correct the other channel.
Leave the checkbox in the ‘Correct’ column unchecked for now.

You can either manually change channels or set a timer to change them with a pre-set interval.
The setting for ‘Correction mode’ will be shared with the ‘Switch Settings’ in the ‘Electronic Optical
Accessories’ dialog described above. If you change either one, the other one will be changed as
well.
Press ‘OK’ to close the options dialog box.
Start measuring by pressing the ‘Start’ button in the upper left corner of the screen.
