1 Introduction
GL SpectroSoft is optional evaluation software with an intuitive user interface and extensive measuring functions for the spectral analysis of light sources, as well as transmission and reflection measurements. Spectral values measured with the MAVOSPEC and the respectively required accessories, as well as externally generated spectra, can be evaluated in accordance with current CIE standards. The software calculates colorimetric magnitudes such as chromaticity in accordance with various CIE standards, correlated color temperature, chromaticity error, peak wavelength, dominant wavelength, color rendering index and index of metamerism. Extensions such as scotopic and photopic values, PAR and PPFD values and MacAdam ellipses can be implemented upon request.
The software is extremely well suited for general light assessments, for laboratory applications and for quality assurance in production. The configurable desktop can be adapted to the respective measuring task, and displays only the required information in a clear-cut fashion. Various program versions are available to match different requirements.
1.1 System Requirements

5. Now you can run the GL SPECTROSOFT.
In the upper left corner there is a description of the currently running program options. Below you will find the icons bar for all functions of the program.
4 Basic Function Tool Bar
The different functions are accessible depend on the version / license of the program.
1. 2. 3. 4 . 5. 6. 7. 8. 9. 10. 11. 12. 13. 14. 15.
1. Open: previously saved measurements can be open,
2. Save group: all currently open / active measurements can be saved in one file
3. Zoom max optimizes the view of the whole spectrum chart in the
current window size.
a) Using the mouse wheel you can zoom image spectrum +/­ b) Hold Y and move the wheel to change the view in the Y-axis c) Hold X and move the wheel to change the view of the X-axis d) Click twice on the chart box and the view options set to max zoom
4. Measure To make measurements, or simply press the space bar. Additionally, the GL SPECTIS 1.0 is equipped with a trigger button located on the side of the body.
5. Continuous sets the measurement procedure in continuous mode according to preset parameters, integration time and number of repetitions. This allows for continuous monitoring of changes in the spectrum under certain conditions. To stop click Continuous again.
6. Serial measurement interval. Allows you to performa series of measurements with a programmed time interval (see serial measurements chapter).
7. Serial measurement count. Allows you to performa programmed count of measurements (see serial measurements chapter).
8. Config button allows access to set the basic parameters of measurements such as:
a) integration time; b) number of repetitions of the measurement c) data save path d) range of spectral measurement
9. Indication of the temperature.
10. Indication of the signal level.
11. Transmition/Refectance mode
This mode allows to make comparative measurements. Reference mesurement is triggered using REF button. Next measure triggered with M button is compared with the reference measurement and signal data are shown as a percent of referens signal.
12. Background mark a current measurement as a ambient light measurement. Next user can using context menu substract selected background signal from another measurement to compensate ambient light. In result next tab is created with the signal after an ambient light substraction. Thistoolisusefulwhen you can notcompletelyeliminate an ambient lightduring the measurements.
13. Background const works in smilar way like background but marked ambient light is substracted after measurement and final signal after substruction is presented immediately.
14. Relative mark a current measurement as a reference signal. Next using Relative View button user can trace how photometric and radiometric parameters of the signal are changing. Results windows shows parameter differences.
15. Relative view turn on/off relative view in results window when relative mode in active.
4.1 Serial measurements
1. Start/stop serial measurements
2. Interval between measurements
3. Measurements count
GL_SpectroSoft allows to program the serial measurements with defined interval and measurements count.
1. Continuous button starts/stops continuous and serial measurements. Continuous measurement (when interval and count is set to 0) triggers the
measurements one after the other and shows spectrum on the same chart. The function is useful to trace change of spectrum and chromaticity parameters of a light source.
Serial measurements are also triggered by continuous button but when interval or count is set to a value other than 0. In this case results are shown in separate graphs.
2. Interval - interval between measurements in seconds. Measurements are triggered one after the other when interval is set to 0.
3. Count - number of measurements to do. When set to 0, measurements loop can be stopped by continuous button. During serial measurements Count filed shows the current number of measurements to do.
The program allows also to set the start time of series measurements with interval and measurements count.
It can be set from Action->Set continuous start menu:

7 TOOLS
7.1 Bin Editor
Binning groups can be defined by Bin Editor tool (Tools->Bin Editor)
In the first tab user can defain xy criterions. Each row is definition for one polygon which determines location of x, y parameters.
Columns meaning:
1. Name of a group.
2. x coordinate of the first point of the polygon.
3. y coordinate of the first point of the polygon.
4. x coordinate of the second point of the polygon.
5. y coordinate of the second point of the polygon, and so on.
6,7. The third point. 8,9. The forth point. You can specify more points if it's needed.
Definition of binning groups may be saved to or load form a text file. Software always use the last used group which path is shown above the table. Sometimes it's easier to edit or import binning groups directly to a text file. Sample text file structure is presented below:
5U 0.437 0.389
0.442 0.398
0.448 0.400
0.443 0.391
6U 0.442 0.398
0.447 0.408
0.453 0.409
0.448 0.400
7U 0.447 0.408
0.451 0.417
0.458 0.418
0.453 0.409
8U 0.451 0.417
0.456 0.426
0.462 0.427
0.458 0.418
Names and values in the file are separated by the tab character. Last selected set is stored in the file C:\GL Optic\GL_Spectrosoft\default\binning.pbp.
Brightness groups are stored in similar way. You can edit them, save and load using the second tab in Bin Editor.
Columns meaning:
1. Name of a group.
2. Brigthness minimum value.
3. Brigthness maximum value.
Sample text file structure is presented below: JZ 61 71 KX 71 82 KY 82 97 KZ 97 112
Names and values in the file are separated by the tab character. Last selected set is stored in the file C:\GL Optic\GL_Spectrosoft\default\brightness.plp.
When binning and brightness groups are defined, the appropriate names are presented in results window and comparison table for each measurement.
7.2 Pass/Fail Editor
Turn on/off pass/fail check
Selectsthe parametersto Setrange (min-max )

Binning and
monitoring
Pass/Fail tool (Tools->Pass/Fail Editor) allows to define user conditions which light should meet and should be checked after a measurement.
Prepare conditions or open previously prepared and turn on pass/fail function.
measurement as a reference signal and find similar with defined
brightness
After measurement in results window and comparison table pass/fail check results are presented. Each parameter which was selected to monitoring is shown as a:
- green - when meets conditions,
- red - when does not meet conditions,
what provides user with detailed information which parameters do not meet selected conditions.
Additionally Pass/Fail parameter shows the overall result of the test (PASS/FAIL). Using this parameter and the comparison table user can divide or compare measurements in an easy way.
8 Reports
A report template is a text file in HTML format. It can be created in any text or HTML. A generated report is opened in default HTML browser.
9 Practical Notes
Make sure that the integration time is properly matched to the level of the tested
source. The best results are obtained by measuring between 40% and 90% signal level. The value of the signal is visible on the top bar after each measurement.
If recommended conditions and time of measurement allows set repeated measure-
ments. This helps to reduce the impact of noise on the measurement results.
When measuring narrow band light sources like LEDs set limited spectral range of
the measurement. This significantly reduces the influence of stray light on the measurement results.
