WebJul 17, 2024 · To measure this increase in brightness, it makes sense that we need a device to measure the number of photons in the visible spectrum, and this is how light meters work! Light Meters. A modern light meter uses a semiconductor like silicon or cadmium sulfide to measure light. When photons strike a silicon photodiode, it creates a very small current. WebCGS units. 10−4 ph. The lux (symbol: lx) is the unit of illuminance, or luminous flux per unit area, in the International System of Units (SI). [1] [2] It is equal to one lumen per square metre.
