Abstract

A compact and miniaturized Fourier transform photoluminescence (PL) spectrometer is provided comprising five functional modules, which are all mounted on a same baseplate: (i) a sample placement module for positioning and spatially adjusting the sample to be tested, which includes a 3-axis stage () and a position mark () for the expected front surface of the sample being tested. The stage is employed for positioning the sample directly or a low-temperature optical cryostat that contains the sample (said sample and cryostat being not parts of the spectrometer), the position mark indicates the pre-aligned position for the projection of the sample's front surface in the horizontal plane; (ii) a built-in pump light source module for generating PL signal, which includes two lasers () and () with different laser wavelengths, the lasers' output can be selected on request in the wavelength range from ultraviolet to near-infrared.
