Laser Beam and Dot Relative Brightness Comparison
Enter the wavelength and output power of two lasers in order to compare their relative beam and dot brightness.
Human eyes are most sensitive to wavelengths close to 555nm with colors appearing dimmer the further away they are from that peak.
The Earth’s atmosphere will scatter different wavelengths by different amounts through Rayleigh Scattering causing beams in air to have a different apparent brightness than dots produced by the same lasers.
