Features & Capabilities

Light Analyzer is an open source physics data logger designed to capture and analyze light spectra using a mobile device's front or back camera, or from image files. It utilizes diffraction gratings and other physical apparatus to measure the intensity and emission spectra of various light sources, including sunlight and artificial lamps.

Built on HTML5 and Ionic 4, the extension provides real-time data recording features, automatic camera permission management, and compares analyzed data against theoretical spectra from reputable databases. Its development is supported by the Ministry of Education of Singapore and the National Institute of Education, contributing to hands-on physics education and joy of learning. This tool is inspired by contributions from the vibrant Open Source Physics community and serves as both a teaching aid and experimental device for physics enthusiasts and students.

User Reviews

Light Analyzer app offers a novel approach to spectrum analysis using smartphones but is hindered by outdated calibration requirements, poor recognition of common light sources, and unreliable detection of fluorescent lights. Users find the UI unintuitive and the app crashes frequently, while the automatic camera controls and IR filters cause inaccuracies. Despite these issues, some users acknowledge its innovative potential and usefulness under ideal conditions with fluorescent lighting.

Pros

Innovative concept aimed at analyzing light spectra using a smartphone camera.
Works well and produces insightful results when calibrated correctly, especially with fluorescent light sources.
Useful for basic spectrum metering when the conditions are ideal.

Cons

Calibration requires specific light sources like fluorescent and gas lamps, which are outdated and not readily available to many users.
Does not recognize or calibrate properly with common modern light sources; app often fails to detect fluorescent lights despite needing them for calibration.
User interface is poor—lacking camera preview, no clear instructions, and it is difficult to navigate or back out of the app.
Inconsistency and inaccuracy in readings due to automatic camera features and IR filters in phone cameras affecting measurements.
App crashes or freezes frequently, reducing reliability and usability.

Recent reviews

This app is ingenious. I think the developers are on to something here. After lots of effort and lots of trials and errors, I finally got this app to work for me. I couldn't get consistent results with my homemade contraption, but I did get it to work. My suggestion is they are going to have to make-and-sell the adapter that fits on the cell phone. Next, they will have to find a way to calibrate the app to adjust for different cell phone cameras. This way, the user will get good results.

Does not work. Placed diffraction grating over lens, aimed at fluoro, pressed "Calibrate" and it reported fluoro light does not exist. Tried several lights in the home. Rotated the grating at angles to see if this made a difference Nope.
