GONIOPHOTOMETERS IN HORTICULTURAL LIGHTING

Horticultural lighting is the standard term used when lights are used for growing plants. Instead of lumen, data is displayed in PPF value, which consists of number of photons radiated by a light source in the photosynthetically active wavelength interval 400-700 nm. As all Viso measurement solutions use fast spectrometer sensors, the PPF can be calculated for any of your measurements.

You might think this kind of data is not necessary for general lighting applications, but if you work on illuminating open spaces like hotel lobbies, which include plants in the architecture, you might be required to specify PPF values.

Viso technology even allows you to generate 3D files in PPFD (photon flux density) as IES and LDT files. This way, you can use existing lighting CAD software, such as Dialux and AG132, to create your horticultural planning.

WHY GETTING your own lab

  • Horticultural lighting is all about dosing light evenly to every plant – and avoiding loss of light. Modern light planning demands detailed light output files for every lighting fixture.
  • 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

Horticultural 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) 

Photometric setup

Choose your preferred units
Switch between photometric and horticultural units on any measurement. Adjust your spectral output region to PAR or any other interval

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
