are also known as: lighspectrometer, photospectrometer or in general spectrometer. By a spectral analysis of light rays through prisms or refractions at the grid with downstreamed light sensitive arrays (photodiodes), it is possible to measure the intensity of light as a function of the wave length.
From this data it is possible to determine extensive light-technical parameters by the respective mathematical algorithms. This way the color rendering index can be measured, as well as the color temperature and many many more values. This makes these innovative light meters more than just a CCT-meter or luxmeter.
Smart devices like an iPhone or an iPad with iOS operating system, but also Android devices nowadays have enough computing power to perform these arithmetic operations in real time. Additionally they also have a high quality display.
So what could be better than using these functions for a spectrophotometer.
For the smart spectrophotometer an additional sensor is needed that performs the physical implementation and transfers the individual readings via Bluetooth to the smartphone. There you just have to install the right App from the App- or Playstore and you are ready to go with the spectrophotometer out of your jacket.
