摘要：

A thermal lensing system using photodiode array detection is described for low-level molecular absorbance measurements. The beam profile is converted for use in the frequency (Fourier) domain rather than the spatial domain since this format seems to provide superior presentation. The effects of laser power and other design considerations are discussed.
