GL Spectrosoft is a PC-based analytical software designed for use in the laboratory, in the field, in production quality control and for general light measurement purposes. It is designed to work in conjunction with your GL Spectrometer to enable fast and efficient light analysis.

Designed to turn raw data into powerful, easy-to-read information, GL Spectrosoft presents your data in clear graphical charts and tables. What’s more, the software includes configurable pass/fail criteria and the ability to easily present and share results through its structured reporting formats.

GL Spectrosoft is modular, meaning you only pay for what you need. GL Spectrosoft Connect is included with all GL systems as standard – all other versions are optional.


Included with all GL systems – supports entry-level applications.


Entry-level light analysis and reporting for users with basic light evaluation needs.


Powerful light analysis for professional lighting evaluation and advanced reporting capabilities.


A laboratory quality tool for advanced spectral analysis, comparisons, testing and customised measurement setups.

GL Spectrosoft Automation

The GL Spectrosoft Automation is an Add-On for the GL Spectrosoft Light Measurement Software. The GL Spectrosoft Automation allows the ability to automate complex operations and supplements whilst accelerating the measurements of additional information such as luminous efficacy and temperature. The GL Spectrosoft Automation minimises errors caused by the misalignment of the GL Optic equipment being used, ensuring accurate, reliable results.

Key features: 

Set Operation Sequences

  • ‘Drag and Drop’ Interface allows you to preset a complete sequence of operations, such as “cooling temperature” or the “current and voltage” before a measurement with the use of programmable peripheral devices.
  • Choose form the relevant measurement options from the list of available operations and create a measurement script which will be automatically executed by the software.

Data Fusion

  • Collect data from external devices and integrate all your critical information together in a single measurement report
  • Set parameter sand check the influence of the current or temperature on the performance of your lighting product and create a comprehensive analysis summary.

Automate Complex Operations

  • The Automation add-on supports programmable power supplies, current sources, multimeters and temperature controllers.
  • Different current levels or temperature conditions can now be monitored and measured with the use of automation script editor
  • Select from a list of support devices to have custom integrations of your own device developed for you

GL Spectrosoft Automation Usage

Spectrosoft Automation was specifically designed to control and manage multiple complex devices and ensure results are obtained efficiently and easily. This software works hand-in-hand with GL Optic’s products and allows a range of instruments to be used simultaneously without creating a bigger workload or increasing the time it takes to obtain results.
