Saving time in each measurement is key to making the most of your light measurement lab. Full Viso measurements typically takes 1-15 minutes. But how can accurate measurements be so fast? Several components go into making the complete solution. Careful […]

New: LabPower

LabPower is a combined AC power supply and power analyzer – designed to work with all Viso Light Measurement systems.

AC mains feed is not always stable and does not always stay at the rated voltage and frequency. To comply with measurement standards (such as IES LM-79 and CIE S 025), your devices must be tested under controlled conditions with specific tolerances.

LabPower will provide a pure sine wave feed to your light source while maintaining the voltage and frequency conditions.

  • LabPower is a dedicated Viso 250 W AC power supply and power analyzer
  • Full integration with any Viso light measurement system
  • Complies with EN13032/CIE and S 025/LM79
  • Optional remote voltage sensing for optimal accuracy

Portable light measurement unit

The smallest Viso measurement system, the award-winning ” LightSpion“, makes advanced light measurements accessible to almost anyone. Furthermore, the portable system can be taken anywhere – even on flights.

Simple, yet advanced: The LightSpion measures all the spectral qualities you dream of and light distribution in up to 8 c-planes. In addition, it automatically compensates for ambient light. Thus, it is possible to measure outside the laboratory with reasonable precision.

The LightSpion uses the same advanced software as other Viso systems. With the user-friendly Light Inspector software, you will be able to analyze, correct and communicate your results efficiently and competently.

Design your own, customized flicker signal. Choose your waveform (square, sawtooth, triangle, sine and cosine) and add frequency, modulation depth and duty cycle. Then watch the result with the built-in LED 3000 K (CRI 80) light source.
