About Microcandelas
The microcandela (µcd) equals 10⁻⁶ cd. LED indicators in standby or low-power mode: many SMD status LEDs operate at 1-100 µcd when current-limited to 10-100 µA. Also the typical sensitivity threshold of modern photomultiplier tube assemblies. 1 µcd = 10⁻⁶ cd.
About Violle
The violle (Vl) ≈ 20.17 cd is the first photometric unit not based on a flame source, proposed by Jules Violle in 1881 and adopted by the CGS system. Defined as the luminous intensity of 1 cm² of platinum at its solidification point (1 768 °C). Used historically in French and international photometry before 1948. 1 Vl ≈ 20.17 cd.
