描述
The app uses the advanced capabilities of your smartphone's camera sensor, combined with sophisticated algorithms, to as accurately as possible analyze the incoming light and determine its dominant wavelength. This technology opens up a world of possibilities, allowing you to delve into the intricate details of the light spectrum in our environment.
For light with only one wavelength, such as the light from a regular colored LED, the dominant wavelength corresponds to the wavelength of that light.
Measuring Light
• Find a white or gray surface (a plain piece of white paper works well).
• Point your camera at the surface, ensuring it is lit by only the light source you wish to measure.
• The app will display the dominant wavelength of the light in nanometers (nm), the frequency of the light in terahertz (THz) and the period length of the light in femtoseconds (fs).
Automatic Warnings
The app provides helpful warnings when the conditions are not ideal for accurate measurement, to help you get the best results.
What is 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. If the light only has one wavelength, such as the light from a regular colored light emitting diode, LED, the dominant wavelength will of course correspond to the wavelength of that light source.
How Accurate are the Measurements?
To measure the dominant wavelength of light accurately is more complex than it might appear. On a smartphone or tablet it is complicated further by the fact that all devices are different from each other. See the measurements as god approximations. Make sure that you always use a white surface and that only the light that you want to measure hits that surface. Also, avoid any shadows or reflections from your hands or your device. If you do that, the measurements shall be fairly good estimations. And for relative
measurements, i.e. comparing the dominant wavelength between different light sources, with the same smartphone or tablet, the measurements shall be good if the conditions above are met.
Please note that the smartphone cameras have limitations when it comes to distinguishing between different very short (UV, ultraviolet), or very long (IR, infrared) 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.
The app now supports 40 different languages.
Free for a Limited Time
