The candela, symbol cd, is the unit of luminous intensity in a given direction; its magnitude is set by fixing the numerical value of the luminous efficacy of monochromatic radiation of frequency 540 x [10.
A monochromatic radiation emitted by a laser diode, by means of an optical fibre, is divided into two parallel beams, one of the optical (reference) beams goes, through optical fibre, round the measuring structure of the refraction angle by SPR technique and reaches an optical adder.
For monochromatic radiation measurements near 365 nm, the out-of-band response is not important and both meters can make measurements with little error.
