JTC 09 (D1/D2/D3/D6): CIE system for Metrology of ipRGC influenced light response
This International Standard will define spectral sensitivity functions, quantities and metrics to describe radiation for its ability to stimulate each of the five photoreceptor types that can contribute, via the melanopsin-containing intrinsically-photosensitive retinal ganglion cells (ipRGCs), to retina-mediated non-visual effects of light in humans.
This International Standard will be applicable to visible optical radiation in the wavelength range from 380 nm to 780 nm. In addition, this Standard will include information concerning the effects of age and field of view (FOV) when quantifying retinal photoreceptor stimulation for ipRGC-influenced light (IIL) responses.
This International Standard will not give information for particular lighting applications, or for the quantitative prediction of IIL responses.
This International Standard will not address health or safety issues such as those resulting from flicker or photobiological safety and will only relate to retinal photoreception.
