With the release of SpecWin Pro 5.0, the comprehensive software for all spectrometers from Instrument Systems, the company presents a series of significant enhancements that further improve accuracy, flexibility, and efficiency in spectral light measurement.
Expanded Goniometer Functions for Complex Beam Characteristics
The update will primarily focus on the goniometer module, which has been expanded with several powerful new functions. A notable addition is the new Sequence Calculator, which is of particular interest to luminaire manufacturers: It facilitates the calculation of multiple goniometric measurement sequences recorded with different orientations of the device under test (DUT). This allows complete characterization of luminaires with bidirectional or complex radiation characteristics.
Additionally, the module provides automatic alignment compensation and determines the minimal calculation error between sequences. The extended interpolation of measurement planes ensures even more precise beam data, which can be exported as usual in the EULUMDAT (LDT) and IES (IESNA LM-63) exchange formats. Furthermore, the calculation of the Unified Glare Rating (UGR) has been aligned with the lighting design software “Relux”, and the CIE 190:2010 standard has been implemented.
Optimized Control of Fast‑Pulsed VCSELs
For applications involving fast-pulsed VCSELs, the integration of high-performance current sources—Source Measure Units (SMUs)—has been significantly improved. It is now possible to take measurements with pulse durations down to 10 µs. Current SMUs from Keithley Instruments and Vektrex Inc. are comprehensively integrated into SpecWin Pro and can be conveniently controlled via the graphical user interface, eliminating the need for external programming. This greatly simplifies laboratory setups.
TOP300: Precision Measurement for AR/VR Micro Displays
Manufacturers of near-eye displays or their components for AR/VR headsets benefit from the integration of the TOP300 measurement accessory. This system, developed specifically for measuring near-eye displays, is typically combined with and calibrated to the high-end spectroradiometer CAS 140D. It features a spot size of ±1.2° and replicates the human eye through its optical design. The viewfinder camera, which is also controllable within SpecWin Pro, enables precise alignment of the measurement spot.
