Goniometer module for SpecWin Pro 1.5

Goniometer module for SpecWin Pro by Instrument Systems GmbH

The Goniometer module extends SpecWin Pro with powerful, angle‑resolved measurement capabilities for LEDs, luminaires, and display backlights. It provides seamless control of Instrument Systems goniometers and synchronized operation with spectroradiometers and photometers, enabling precise characterization of spatial light distribution and color over angle.

Key features

• Integrated hardware control: Operates Instrument Systems goniometers with synchronized detector triggering for accurate, repeatable angular scans.
• Flexible scan setup: Define C‑planes and gamma angles, symmetrical ranges, step sizes, dwell times, and single- or multi‑axis sequences.
• Comprehensive results: Determine luminous intensity distribution, beam angle, center beam candlepower, and total luminous flux via spatial integration. Analyze colorimetric data versus angle, including chromaticity coordinates and correlated color temperature.
• Live visualization: View polar plots, isocandela diagrams, and angular trends in real time to validate setups and optimize measurement time.
• Data export: Generate industry-standard files for lighting design and documentation, including IES and EULUMDAT (LDT), as well as CSV and image exports.
• Reporting and automation: Create customizable reports with project metadata and automate repetitive tasks with reusable templates and sequences for R&D or production workflows.

Typical applications

• Angular characterization of LEDs, modules, and lamps
• Luminous intensity distribution of luminaires and optical assemblies
• Color uniformity and CCT over angle for light engines and backlights
• Verification and documentation for product development and quality control

With its tight integration, intuitive setup, and robust data outputs, the Goniometer module for SpecWin Pro streamlines angular photometric and colorimetric measurements from setup to final report.
