About this app

Aspectra is a system of some applications, utilizing Android devices and some additional hardware.
Purpose of these applications is to observe, display and analyze the spectrum of observed light

Aspectra mini is the base application in Aspectra system.
The Android device, with additional low cost spectrometer, can be used to observe the spectrum of light. Spectrum is shown as intensity plot. Every plot can be saved for the future analyze with another applications: Aspectra viewer (explorer for spectra) Aspectra analyzer (editor for spectra).

Possible applications:
teaching spectroscopy
chemical analyze
distance measurement
control of LED light source color
astral spectroscopy

The application is a very good start, it would be nice to lock the vertical scale manually, and the horizontal scale could have a colour spectrum for reference. both scales could be calabrated against a known source. Time date and location would also be useful for measuring. Then this app could be used more objectively.

I have been experimenting with having this app. approximate a PAR Meter. Assuming a PAR meter reads energy in the 400nm to 700nm range,, this app shows you the energy spectrum from about 200 to 800nm, so it shows you pretty clearly what frequency your light source is emitting. My next task is to find the correct spectrum and balance of color that makes up the perfect PAR value balance.

Best app to analyse the spectrum of visible light. It work properly but the value of wavelength and intensity do not mach with results. But anyway only one real app for spectrum analysing on android.
