Light Spectrometer Wavelength

This application analyzes light to determine its dominant wavelength in nanometers, frequency in terahertz, and period length in femtoseconds. It provides real-time measurements and allows users to save their findings with notes. The app is designed for measuring colored light sources.

Highlights
  • Measures dominant wavelength (nm)
  • Measures frequency (THz)
  • Measures period length (fs)
  • Real-time measurement
  • Save measurements with notes
  • Optional calibration

Measures light spectrum to determine the dominant wavelength in nm, frequency in THz and period length in fs. DOMINANT WAVELENGTH Dominant wavelength is a concept commonly used in the field of color science and perception. It refers to the wavelength of light that appears most prominent or dominant in a given color mixture or light source. In other words, it is the wavelength that our eyes perceive as the primary color in a mixture of different wavelengths. For light with only one wavelength, such as the light from a colored LED, the dominant wavelength corresponds to the wavelength of that light. KEY FEATURES • High accuracy • Real-time measurement • Measures light wavelength in nanometers (nm) • Measures light frequency in terahertz (Thz) • Measures light period length in femtoseconds (fs) • Easy to use • Save measurements with notes • Supports 40 languages, including english • Optional calibration for enhanced precision MEASURING 1. Find a white surface, such as a plain piece of white paper 2. Point your camera at the surface illuminated by your target light source 3. The app gives you accurate measurements in real-time LIMITATIONS Smartphone cameras have limitations when it comes to distinguishing between different very short, or very long wavelengths. More specifically, on many devices the accuracy below 465 nm and above 610 nm is very limited. This is due to the physical camera sensors in the devices. An automatic warning appears on the screen for these short and long wavelengths. WHITE LIGHT Note that is not meaningful to measure the dominant wavelength of white light as white light consists of a wide range of wavelengths, with no wavelength dominating. This app is made for measuring colored light. If you are interested in determining the color temperature of white light, please instead use our popular White Balance Kelvin Meter app. COLOR OF SURFACES If you want to measure the color of a surface or material, rather than of light, please instead use our popular Colorimeter Camera Color Meter app. Privacy Policy, https://spectrometer.contechity.com/pp.html End User License Agreement, https://spectrometer.contechity.com/eula.html CONTACT I value your feedback.

Verdict

The call

The clearest difference is price: Light Spectrometer Wavelength at Free against SpectraMania's $7.99. Light Spectrometer Wavelength also leads on update cadence (every 2 months vs every 6 months) and ratings volume (96 vs 4). SpectraMania's advantage is in-app purchases (none vs 7). On review sentiment, ads, device support and iOS requirement there is nothing between them.

ReceptionRating · Positive reviews · Number of ratings

Light Spectrometer Wavelength holds the better App Store score, 4.2 against 4.0. That said, the two scores are not equally well evidenced: Light Spectrometer Wavelength has 96 ratings behind it against 4, so its average is the more settled of the two. Written reviews complicate that: 71% of Light Spectrometer Wavelength's written reviews are positive against 75% of SpectraMania's, so the app with the better star average is not the one people write more warmly about.

UpkeepUpdate frequency

Light Spectrometer Wavelength ships an update every 2 months, SpectraMania every 6 months. The most recent releases landed on November 3, 2026 and October 30, 2026 respectively.
