Goniophotometers for entertainment lighting

Entertainment lighting has developed into a complex field of solutions including video, lighting and control technology that provide and facilitate great visual experiences in sporting events, concerts, museums, film, TV, convention centers etc.

Professional providers of lighting equipment must support clients with lots of photometric data. A Viso solution will give you all of the of the photometric data you need and even more.

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

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

RGB 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) 

Illuminance

Illuminance plot
Illuminance (lx/foot-candles) in various distances (m/ft) from the light source is often an essential design parameter

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

Further outputs

Fundamental radiation data

  • Total luminous output
  • Peak Candela
  • Beam angle
  • Polar light distribution curves
  • Linear light distribution curves

Color and color deviation data 

  • CCT / Correlated Color Temp. [K]
  • CRI / Color Rend. Index / Ra (1-14)
  • TM30-18 indices and graphics
  • CQS index and graphics
  • SCDM (MacAdam steps)

Lighting design and data export

  • Isolux/iso-candela plots
  • Full raw data export to MS Excel etc.
  • Optional web-based tracking system
  • Customizable PDF reports

Power and warm-up data

  • Wattage [W] and efficacy (lm/W)
  • Current [A] and voltage [V]
  • Current and voltage THD [%]
  • Warm-up time and variation
  • Automatic stabilization

Popular additions

Add great tools to your system, capture more data and ease your work

The LabFlicker instrument records all contemporary TLAs (temporal light artifacts): Flicker and stroboscopic effects including PstLM. LabFlicker connects to all Viso systems

Add a LabTemp 3-port temperature probe system for monitoring temperature of device under test

Upgrade your existing sensor to provide a broader measurement range (eg. UV) or a wider sensitivity ranges
