743 nm to RGB & Color Calculator
Convert 743 nm monochromatic spectral light into exact digital sRGB, CIE 1931 tristimulus XYZ coordinates, THz frequency, and photon energy.
Why You See This Color (743 nm)
At 743 nm, photons interact exclusively with Long-wavelength sensitive (L) photoreceptor opsins in the fovea centralis. With a frequency of 403.489 THz and lower photon energy (1.669 eV), this stimulus yields the deep, saturated red sensation of monochromatic ruby and diode lasers. Near the 700–750 nm boundary, eye sensitivity tapers toward the infrared threshold.
