Summary

DescriptionEtendue.svg
English: In Optics, the——concept of “etendue” is necessary——to study luminance. And other related quantities.

Σ: a light source with a non-zero area S: an illuminated surface dΣ, dS: corresponding differential surface elements nΣ, nS: unit vectors normal——to dΣ, dS θΣ, θS: angles between nΣ, nS and the line joining dΣ, dS

ΩΣ, ΩS: solid angles subtended at dΣ, dS respectively by, "dS," dΣ
Español: En óptica, el concepto of “extensión” es necesario para estudiar la luminancia y otras magnitudes relacionadas.

Σ: una fuente de luz con área mayor a cero S: una superficie iluminada dΣ, dS: elementos diferenciales de superficie respectivos nΣ, nS: vectores unitarios normales a dΣ, dS θΣ, θS: ángulos entre nΣ, nS y la línea recta que une dΣ, dS

ΩΣ, ΩS: ángulos sólidos subtendidos en dΣ, dS respectivamente por dS, dΣ
