This can be extended to a range of 310 to 1,050 nm under artificial conditions A continuous 1064 nm laser source appeared red, but a 1060 nm pulsed laser source appeared green, which suggests the presence of second harmonic generation in the retina

The foveal sensitivity to several near-infrared laser wavelengths was measured.

It was found that the eye could respond to radiation at wavelengths at least as far as 1064 nm
ينفذ عبر الخشب. ينتقل في خطوط مستقيمة
This is called the visible part of the spectrum
