Light Measurement Technology

At Viso we create innovative solutions for the lighting industry. We maintain the high quality of our products and utilize the most modern technology and materials. We develop new features of our products, expand the functionality of the software and create useful fittings to accommodate our customers’ measuring conditions.

To measure light, i.e. to capture the luminous flux emitted from a light source into the room, it is essential to either provide conditions of darkness or to separate the background lighting from that of the measured light. While we recommend making measurements in the absence of additional light, Viso technology gives you the option of ambient light correction in the Viso Light Inspector software. The data acquisition has two steps: first the background light is measured on its own when the sample light is switched off, then the measurement is repeated with the light source illuminated. Using our unique algorithm, the background radiation measurement is then subtracted from the overall illumination and the resulting measured light distribution for the sample light is presented.

Most luminaire manufacturers are primarily interested in photometric data such as flux and light intensity.  Lighting designers and engineers are equally concerned with the sensory aspects of light such as color temperature, color coordinates and color rendering index (CRI).  We are using spectrometer sensors, as opposed to conventional photometers, because conventional photometers cannot give all photometric data of a light source. Instead, our spectrometer sensors transform Viso’s systems into portable laboratories with multiple functions which can determine the spectral data of the light sources.  In this way, we can incorporate the interests of a wider group of clients who need fast and easy laboratory quality light measurements.

Viso Systems use spectrometer sensors based on cutting-edge, transmission grating technology which obtains the visible spectrum of the tested light source with a high-speed of 30 seconds per C-plane. This makes the data acquisition time for a light measurement exceptionally fast.

Simplicity and functionality are the two keywords that describe the Viso Light Inspector Software. The capturing of light distribution is displayed in real time, allowing the user the possibility to participate in the process of data acquisition. The user interface of the software extremely intuitive and thereby improves the ease and efficiency of workflow.
