Shortcuts to our most popular solutions

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

The new “LabSensor UV-VIS” measures both UV light and visual light simultaneously. The new sensor works with the LabSpion and BaseSpion goniometer solutions.

Our most versatile goniometer system. Measure light sources up to 1,5 m (2,0 with extended tower) and 25 kg. Measure visual light with LabSpion VIS and both UV light and Visual light with LabSpion UV-VIS

New: Labarazzi

Labarazzi flicker generator

The Labarazzi® TLA generator is your tool to generate flickering light for test and demonstration.
Use the preset flicker signals or design your own signals. Test your flicker meter or your video camera.
Use Labarazzi flicker generator in quality tests, lighting education and in research projects

  • Demonstration of flickering light – in education and sales
  • Temporal Light Artifact research
  • Test of digital cameras and video cameras for TLA interference
  • Flicker tester calibration

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.

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.
