VISO BaseSpion Benchtop Goniophotometer

VISO BaseSpion Goniophotometer

The BaseSpion from Viso Systems is a mid-sized, bench-top, type C goniophotometer. It features motorised, two-axis motion and can be used for measuring small to medium lamps and luminaires up to 22cm square, 54cm diameter and 9kg. An optional high speed photometer accessory allows you to also measure photometric flicker.

What Photometric & Colorimetric Parameters Does BaseSpion Measure?

  • Total luminous flux (lumens)
  • Useful lumens (per EU 1194/2012)
  • Zonal flux (lumens)
  • Stabilisation time (minutes)
  • Peak luminous intensity (candelas)
  • Cone & ISO illuminance (lux)
  • PPFD (photon flux density)
  • Unified glare rating (UGR)
  • CIE 1931 & 1960 chromaticity coordinates (xy, uv, Duv)
  • Correlated colour temperature (CCT, Kelvin)
  • Colour rendering index (CRI, Ra & R1-14)
  • Colour rendering index (IES TM30, Rf & Rg)
  • Colour rendering (CQS, Q1-14)
  • Spectral power distribution (360-830nm)
  • Beam angle (degrees)
  • Beam shape (luminous intensity versus angle of inclination & azimuth)
  • Power consumption (Watts)
  • Power factor
  • Luminous efficacy (lumens/Watt)
  • Output formats: IES, LDT, CSV, customisable PDF

Fast, Accurate & Versatile

The BaseSpion is a versatile, benchtop goniophotometer suitable for testing small to medium light sources and luminaires. BaseSpion is perfect for testing and generating .ies or .ldt photometric data files from lamps, luminaires and LED modules, with a maximum sample size of 540mm diameter or 220mm square and with a maximum sample weight of 9kg. With both inclination and azimuth (C-plane) axes motorised, a lamp can be measured quickly and convenientl (scan times are as short as 30 seconds).

Being based on a spectroradiometer (rather than on a traditional photometer), BaseSpion not only gives you information on total luminous flux (lumens), peak intensity (candelas) and beam shape, it also tells you the colour temperature (CCT, Kelvin) and colour rendering of the light source. The BaseSpion features an integrated power analyser and is supplied with its own reference lamp which can be used to verify your calibration at any time without the need for external support. Control of the BaseSpion is from a (customer-provided) Windows PC running VISO's Light Inspector software - click here for details.


EU Eco-Design Regulations

VISO LabFlicker Flicker Photometer

The BaseSpion supports the EU eco-design regulations (EU No 1194/2012), which require directional lamps to be measured in a 90° or a 120° cone. A simple selection of the measurement cone of either 90° or 120° sets the automatic calculation. The measurement of so-called "useful lumens" requires a goniophotometric measurement; useful lumens cannot be measured using a traditional integrating sphere.

Optional Flicker Measurements

You can add a flicker measurement capability to your BaseSpion goniophotometer by choosing an optional high speed photometer (shown to the right). The VISO LabFlicker photometer seamlessly integrates with Light Inspector software to give you the flicker percentage, flicker index, flicker frequency and SVM index for your lamp. The LabFlicker photometer can be used as a standalone device, but its real power is released when used together with the VISO BaseSpion or LabSpion goniophotometers, as all the flicker parameters are
incorporated into the full photometric test report.
