Abstract
1404636 Measuring reflectance photoelectrically BASF FARBEN & FASERN A G 16 Nov 1972 [17 Nov 1971] 52965/72 Heading G1A An apparatus for determining the covering power of paint applied to black and white substrates comprises a casing 1 having two openings 2 located adjacent the respective coated substrates and illuminated by one or more light sources 6, and photo-cells 5 receving light reflected from the respective substrates through openings in boxes 4 which ensure that each photo-cell receives only light reflected from the painted surface through the corresponding opening 2. The photo-resistors 5 are connected in a bridge arrangement whose out-of-balance current indicates the reflectance ratio of the two substrates. Alternatively, the two photo-resistor outputs may be supplied to a differential amplifiers.
