Integrating sphere

With a Viso Light measurement system in your lab, you will not need an integrating sphere. This is why.

A traditional, far-field light measurement lab would need:

–  MEASUREMENT STEP 1: A mirror goniophotometer (PHOTOMETER-based)

–   MEASUREMENT STEP 2: An integrating sphere

–   A large instrument rack

–   A sensor in e.g. 25 meter (80 ft) distance

–   5-6 meter (20 ft) ceiling height in lab 

A photometer does not capture spectral properties. Hence, all data color data such as CCT and CRI need to be measured with another system – typically an integrating sphere (A.K.A. an Ulbricht sphere) fitted with a spectrometer. Consequently, each light source will then need characterization in two steps:
1) The goniophotometer captures light intensities (candela in all directions = light distribution) and lumen package.
2) Then, the integrating sphere captures lumen package and SUMMARIZED color data (integrated spectrum, overall CCT, CRI etc.)

A modern, Viso far-field light measurement lab includes:

–  MEASUREMENT STEP 1: A gonioSPECTROmeter  

–  A PC/laptop

–   A sensor in e.g. 10 – 25 meter (30 – 80 ft) distance depending on the size of your light sources

–  Normal ceiling height in lab 

A spectrometer captures spectral distribution and light intensity. Hence, all data can be captured in one measurement session – a single step for each light source. The Viso goniospectrometer captures light intensities (candela in all directions = light distribution) and lumen package, as well as SUMMARIZED AND PER ANGLE color data (integrated spectrum, overall CCT, CRI etc., color over angle). Consequently, the modern lab is faster and easier to operate and takes up much less space.

Based in Copenhagen, Denmark, Viso Systems has developed and produced high-end light measurement equipment and controls since 2006. We supply the lighting market with innovative light measurement and control technology that is of the highest quality and precision. We simplify the complexity of measurements and control systems by delivering intuitive user interfaces. The implementation of unique technology in our products, for example the fast spectrometer solution that replaces a photometer, puts us on the forefront of smart, fully integrated measurement solutions.

The Viso Light Inspector software is the strongest and most intuitive light measurement software solution in the market. The dashboard provides you with a perfect overview of your measurements – and in real-time. We know that speed of measurement and data production is crucial to your business. Whether you just want to create LDT and IES files or you want more advanced reports, Viso Light Inspector software will provide fast and easily customized outputs.

We develop and improve our products every day – and preferably in interaction with our customers. Your inputs and ideas are important to us. Close dialogue with the users ensures that our systems are always suitable for your tasks and meet new requirements.
