Why You See This Color (741 nm)

At 741 nm, photons interact exclusively with Long-wavelength sensitive (L) photoreceptor opsins in the fovea centralis. With a frequency of 404.578 THz and lower photon energy (1.673 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.
