LabSensor UV Light Measurement System

LabSpion UV-VIS® is a specialized light measurement solution for testing UV light sources as well as ordinary luminaires in the same system. It covers all light source sizes from small lamps and LED chips to large panels and street lighting. The 2-axis LabSpion UV 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. Comprehensive  LDT and  IES  simulation files are standard outputs.

The LabSpion UV-VIS goniometer is the ideal way of measuring a wide variety of light sources ranging from all UV lamps and luminaires to standard fixtures, automotive lights and LED panels. The light source is easily attached to the goniometer and rotation is both quick and silent. The LabSpion UV-VIS handles light sources up to 25 kg and 1.5 m in diameter. The heavy-duty 2.0m-tower version even handles light sources up to 45 kg and 2.0 m in diameter.

The LabSpion UV-VIS system is quickly installed and comissioned. The measuring process is fully automatic with the option of manual operation. Data acquisition from a single C-plane takes 15-30 seconds, which means that 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.
