illuminance2troland: Convert from luminance to troland and effective troland

Description

illuminance2troland convert from illuminance (lux) to conventional retinal illuminance (troland) and effective troland (trolands per effective area). luminance2troland convert from luminance (cd/m^2) to troland and effective troland.

Usage

illuminance2troland(Ev, lumFactor, d=NA)

Arguments

d

diameter in mm

Lv

luminance (cd/m^2)

Ev

illuminance (lux)

lumFactor

luminance factor
