GONIOPHOTOMETERS FOR GENERAL LIGHTING

General lighting can be defined as the functional and decorative lighting that surrounds us all in our everyday lives.

All professional lighting planners need 3D light files to simulate lighting design in workplaces and public spaces. Consequently, providers of professional lighting fixtures and light sources need laboratories to the produce so-called IES and LDT files and lots of other data. In parallel, importers and producers of light sources for household use also need to characterize their products in detail to comply with local legislation.

WHY GETTING your own lab

  • Having your own lab pays off. Our clients generally claim that pay-back time is 6-12 months depending on external laboratory costs
  • Your internal R&D will perform much faster and gain competencies. Better optical solutions and faster time-to-market
  • Build trust in your products and brand and strengthen your client relations by having lots of data ready
  • Having your own lab makes is possible for you to QC products from sub suppliers systematically

YOUR PROFESSIONAL IMAGE

Thorough testing and characterization of your products builds trust. With a lot of detail in your data sheets and presentations, customers will believe in your solutions and your competencies. This true both for your own products and third-party solutions. Viso software makes issuing measurement reports easier than ever. Reports can be fully customized to fit your own corporate identity.

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 - Spectral power distribution

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

Light measurement power curve

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
