GONIOPHOTOMETERS FOR SMALL LIGHT SOURCES

Data sheets for LED components (SMD, COB) includes lots of information about the emitted light. Goniometers from Viso Systems capture all information with a single measurement. The Viso Light Inspector software is the strongest and most intuitive light measurement software solution in the market. The user-friendly dashboard provides you with a perfect overview of your measurements – and in real-time. The software handles automatic goniometer setup and measurement. The Light Inspector has extensive output options and connect directly to MATLAB, LabVIEW, etc.

The Viso BaseSpion system is especially well suited to measurement of RGB LEDs, COB LEDs and SMD LEDs. Fast spectrometer sensors is the technology behind all Viso light measurement systems. Hence, all data is based on full-spectrum goniometer measurements. Measuring is fast: One full plane (= two C-planes) in a 5° resolution is measured in just 20 seconds. As all data is generated by the Viso system, there is no need for subsequent integrating sphere measurements.

The portable LightSpion is an excellent choice for measuring LED components as well as round-symmetrical small light sources such as household light bulbs.

Basic outputs

Light distribution curve

Light distribution curve
With high measurement detail (up to 72 C-planes and up to 0,1 degree gamma resolution) there is data in abundance to plot. 3D plot are included as well

Light measurement Spectrum

Spectrum 
As light is detected with a Viso fast spectrometer sensor, spectral data is recorded in every measurement. A Viso goniometer will even provide ‘color over angle’ data (not possible with an integrating sphere) 

CIE 1931 color coordinate plotCIE 1931 color coordinate plot

CIE 1931 color coordinate plot
The integrated spectrum can be plotted in a CIE 1931 x,y-diagram. Provide your color target, and the color difference (Duv) and the SDCM value (MacAdam steps) are prompted

Power curve from light measurement

Power characteristics 
All Viso goniometers have a built-in power analyzer. The analyzer will help you to determine when light sources are stabilized. Important power data (wattage, efficacy, power factor etc.) are standard
