WebSep 1, 2007 · The photometer consists of a light source (an LED), a light-dependent resistor (LDR) as a detector and a simple amplifier/buffer circuit to make the output suitable to drive a voltmeter. (If a high impedance multimeter is used, the amplifier could be omitted, but it does illustrate an important component of a 'real' photometer.) The LED and LDR ... Webhigh-grade commercial photometer heads from four manufacturers. The f 1’ values measured by three different facilities as well as manufacturers’ data were compared. The results indicate that f 1’ value can change considerably under different measurement conditions depending on the design of photometer. Keywords: Photometer heads, spectral
