    摘要: A method and apparatus determines the thickness of a copper oxide coating of an object by measuring the quantity of light reflected from the object in at least two wavelength zones, and then determining a value for a relationship between those quantities, for example, the ratio or difference of those quantities. The value is then compared to a predetermined, regular correspondence between such values and copper oxide thicknesses to determine the object's copper oxide thickness.

    摘要: A fluorescent lamp which comprises a vacuum-tight envelope provided with electrodes between which discharge takes place during the operation of said fluorescent lamp. The envelope is coated on the inside with a phosphor composition layer comprising: a first light-emitting material having an emission spectrum with a peak in the wavelength range between 465 and 490 nm, or preferably between 480 and 490 nm, and a half width ranging from 30 to 120 nm, or preferably from 70 to 100 nm; a second light-emitting material having an emission spectrum with a peak in the wavelength range between 550 and 580 nm, or preferably between 560 and 570 nm, and a smaller half width than 110 nm; a third light-emitting material having an emission spectrum with a peak in the wavelength range between 600 and 620 nm, or preferably between 610 and 620 nm; and a fourth light-emitting material having an emission spectrum with a peak in the wavelength range between 480 and 500 nm, or preferably between 480 and 490 nm, thereby ensuring high luminous flux and satisfactory color rendering.
