BaseSpion UV-VIS® is a specialized light measurement solution for testing UV light sources as well as ordinary luminaires in the same system – a gonioradiometer or a gonio-spectroradiometer.
It covers light source sizes from small lamps and LED chips to meadium-sized luminaires. The 2-axis BaseSpion 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. The system gives you all photometric and radiometric data in one measurement. There is no need for an integration sphere. C omprehensive LDT and IES simulation files are standard outputs.
By using a goniospectrometer for UV measurements the problem of integrating sphere interior deterioration is avoided.
The BaseSpion UV-VIS light measurement system is the ideal way of measuring a wide variety of light sources ranging from all UV lamps and luminaires to standard fixtures and LED panels. The light source is easily attached to the goniometer and rotation is both quick and silent. The BaseSpion UV-VIS handles light sources up to 9 kg and 56 cm in diameter.
The BaseSpion 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 – and even UV IES-files. You can create your own custom pdf report templates. Read more about the Light Inspector software here.
THE IMPORTANT STRAY LIGHT CORRECTION
All Viso’s UV sensors have straylight correction. As UV spectrometers need high sensitivity to handle low level signals, any small stray light reflections from within the spectrometer must be corrected for optimal performance. At Viso is this done performing a series of calibration test at multiple wavelength detecting all straylight and storing it in the calibration data. All straylight is then in real-time removed from the spectrum using mathematical matrix calculations based on the straylight test data.
COMPARING WITH MIRROR based systems
Mirror-based gonioradiometer or a gonio-spectroradiometer are available in the market. However there are some important advantages of the Viso solution:
