LightSpectrum Pro4.4.0 - App Store

With LightSpectrumPro EVO you can measure the color temperature of a light source without having to spend hundreds of dollars on professional devices. LightSpectrumPro EVO has an error of 2 - 8% compared to existing professional products on the market. in addition to the color temperature measurement in Kelvin, LightSpectrumPro EVO allows you to view the color spectrum of the light being examined with a band ranging from 360nm to 800nm. in addition to the spectrum it is possible to display the position of the white point on the CIE 1931 diagram and to apply a filter for wavelengths to display in overlay on the image captured by the cameras which elements reflect a specific frequency and with what intensity.

Version History This update brings support for all the latest iPhone models, introduces automatic light source recognition for a smarter analysis experience, improves overall performance and stability, and includes several minor bug fixes to ensure smoother operation. 4.4.0 Jun 14 Added compatibility with new devices and operating system
Added reading of RGB values for white point
Added user manual
Improved stability
Fixed minor bugs 4.3.1 02/12/2023 Added the spectrographic analysis mode with the use of the refraction box
fixed minor bugs 4.3.0 07/31/2021 Added a new function that allows you to estimate the value of PAR (Photosynthetic Active Radiation) emitted by the light source. The value is expressed in PPFD (Photosynthetic Photonic Flux Density) in umol/m2/s, which consists of the quantity of PAR that reach the surface of the plant per second.

Fixed a bug that blocked the calculation of the color temperature value on some devices
Minor bugs fixed. 4.0.6 12/14/2019 introduced the measurement of the concentration of blue lights, indicated with the G-Index value that represents the quantity of wavelengths of the colors of light ranging from 350 to 550 nm with respect to the intensity of the complete view. The G-index, indicates the shift towards red or infrared spectrum, therefore a low value of G indicates a large percentage of blue lights, a value greater than 2 indicates that the light under examination has a low concentration of wavelengths between 350- 550 nm 4.0.5 09/16/2019 stability improved
