LabSpion® is a complete light measurement solution that covers all light sources from small lamps and LED chips to large panels and street lighting. The 2-axis goniometer allows the system to measure the entire 3D distribution field for any light source. Using a spectrometer sensor and a built-in power analyzer, the unique Viso technology enables fast measurements and ensures that all data is measured quickly. The system gives you all photometric data as well as data that integration spheres provide in one measurement.

The LabSpion is the ideal way to measure a wide variety of light sources ranging from outdoor fixtures to automotive lights and LED panels. The light source is easily attached to the goniometer and rotation is both quick and silent. Most importantly, the LabSpion handles light sources up to 25 kg and 1.5 m in diameter.

The installation process is very simple too. Place and level the base of the LabSpion on a stable surface, preferably in a dark room. Mount the goniometer arm on the base. The spectrometer sensor is easily mounted on a tripod and is placed at a distance depending on the size of the measured lighting fixture. The built-in laser automatically detects the distance between the two parts, so the alignment is quick and precise. The system is fully operable within 20 minutes.

The LabSpion system is then ready for measurement. Install the Viso Light Inspector software, connect your laptop to the built-in power analyzer in the base, and start measuring. The process is automatic with the option of manual operation. Data acquisition from a single C-plane takes 15-30 seconds, which means that is takes roughly 15 minutes to collect data from all planes.

Measurement data is then automatically saved in a specific folder in the form of fixture files. They are usually exported into PDF, PNG, IES, LDT and CSV formats. You can create your own custom pdf report templates. Read more about the Light Inspector software here.
