IC 2017
We are thrilled to share the results of the world’s largest interlaboratory goniometer comparison – the so-called IC2017. The Technical University of Denmark participated with a Viso system. The results […]
Melanopic EDI
“A high melanopic EDI during the day is usually supportive for alertness, the circadian rhythm, and a good night’s sleep”. This is what the CIE concludes in a position statement […]
LEDs magazine feature
LEDs Magazine asked Viso Systems to contribute with a special feature article for their latest issue. Planned pathogen prevention is key in avoiding installations that lead to a false sense […]
Dialux Evo simulation
Using UV light in germicidal applications is popular. A new video introduces a method that allows you to design UV lighting installations with DIALux Evo 9.2. In this way, you […]
Nichia LED - germicidal violet
There are interesting news from Nichia: A dual purpose LED that offers quality light and germicidal benefits. A strong peak at 405 nm means that this LED can deactivate bacterial […]
Integration time photometry
CMOS (linear image sensor) integration time can be defined as the period over which the spectrometer collects photons in every goniometer measurement point. The length of this time is important: […]
Building your own photometry lab
Traditionally, a photometric laboratory took up lot of space, but a measurement system from Viso will fit in almost anywhere. Many clients ask for advice in terms of lab sizing, […]
Useful lumen definition
New EU regulation requires directional light sources and luminous flux to be measured within a 90° or a 120° cone. Luminous flux measurements are normally done at full 360° in […]
