Abstract
A wavelength modulation spectrometer that can be easily assembled is illustrated. The apparatus, which employs a double beam scheme with two detectors followed by standard electronics, allows the simultaneous detection of absorption (or reflection) spectra and their logarithmic derivatives. The smallest modulation that can be detected has been found to be ∼10−5 Å−1 when the bandpass is ∼2 Å.Keywords
