Figure 4. Transmittance and Absorbance

Double Beam UV-Visible Spectrophotometer

Lambda 365 double-beam UV-Visible spectrophotometer, the light is split into two beams

before it reaches the sample. One beam is used as the reference; the other beam passes

through the sample. The reference beam intensity is taken as 100% Transmission (or 0

Absorbance), and the measurement displayed is the ratio of the two beam intensities.

Lambda 365 double-beam UV-Visible spectrophotometer has two detectors (photodiodes),
and the sample and reference beam are measured at the same time
