When fully light-adapted, the human eye features a wavelength response from around 400 to 700 nanometers, with a peak sensitivity at 555 nanometers (in the green region of the visible light spectrum). The dark-adapted eye responds to a lower range of wavelengths between 380 and 650 nanometers, with the peak occurring at 507 nanometers.
This narrow band of frequencies is referred to as the visible light spectrum. Visible light - that which is detectable by the human eye - consists of wavelengths ranging from approximately 780 nanometer (7.80 x 10 -7 m) down to 390 nanometer (3.90 x 10 -7 m). Specific wavelengths within the spectrum correspond to a specific color based upon how ...
The sensitivity of the human eye to light of a certain intensity varies strongly over the wavelength range between 380 and 800 nm. Under daylight conditions, the average normal sighted human eye is most sensitive at a wavelength of 555 nm, resulting in the fact that green light at this wavelength produces the impression of highest "brightness" when compared to light at other wavelengths.
The wavelengths of visible light range from about 400 nm to about 700 nm. Photopic vision is the scientific term for human vision under normal lighting conditions during the day. This allows for color perception. The cones in the retina help us to see the colors. There are three types of cones in the human eye.
The human eye is sensible to light wave which wavelength is roughly between 400 nm (violet) and 700 nm (red). Wavelengths shorter than 400 nm (ultraviolet, UV) or longer than 700 nm (infrared, IR) are not visible. The eye behaves differently in high or low light conditions: in daylight, for brightness levels above 3 cd/m 2 the vision is mainly ...
Eye spectral response . 13.8. Eye intensity response, contrast sensitivity. Eye light-intensity response. Human eye is capable of responding to an enormous range of light intensity, exceeding 10 units on logarithmic scale (i.e. minimum-to-maximum intensity variation of over 10-billion-fold). Inevitably, eye response to the signal intensity ...
