Ocean Optics with Xplorer GLX Spectrometer Analysis Configuration Screen

Spectrum Preview

When the configuration screen opens, the GLX automatically starts

monitoring and displaying spectrum data in the upper half of the screen.

With this preview, you can immediately see the effect of changes that

you make to parameters. Press to manually stop or re-start spec-

trum monitoring.

Function Keys

Use the function keys to save and clear dark and reference scans and to

close the configuration screen.

F1 Save Dark With the light source off or blocked (so that no light

enters the spectrometer), press to save the dark scan.

F2 Save Ref With “reference light” entering the spectrometer,

press to save the reference scan. Do this after setting the parame-

ters in the Data Acquisition tab (see “Data Acquisition Tab” below).

Your “reference light” may be one of the follow (depending on what

type of measurement you plan to make):

• The Integrated Light Source with a reference cuvette

in place (for

measuring absorbance and transmission of light through a solution).

• A lamp with a known color temperature (for measuring the relative

irradiance of light sources).

• Any light source (if you plan to use only the Intensity and Minus

Dark measurements).

F3 Clear Scan Press to delete the dark and reference scans.

F4 Close Press to close the configuration screen.

Navigating in the Configuration Screen

The configuration parameters and options are contained in three tabs:

Data Acquisition, Lamp, and Time Acquisition.

To navigate between the tabs, press the left and right arrow keys. (Note

that the Time Acquisition tab will not be available until you have saved

dark and reference scans.)

Navigate within a tab by pressing the up and down arrow keys to high-

light different parameter and options. To change the highlighted param-

eter or option, do one of the following:

• Press or to change the value of the parameter by 1.

• Press to make the parameter editable. Type the desired

value. Press again.

• Press to toggle a two-choice option.

• Press to open a pop-up menu. Use the arrow keys to highlight

the desired menu option. Press again.
