The present invention provides a substrate collecting device that includes a first stage on which a sheet is placed with a plurality of substrates facing downward, an sampler which carries out a predetermined operation on some of the substrates, which are disposed at predetermined positions, from above the first stage thereby to cause the substrates to come off from the sheet and fall, an optical system and a collector disposed below the first stage, and a second stage, which integrally moves the optical system and the collector in a horizontal direction. The second stage is capable of positioning the optical system and the collector at two positions at which the optical system or the collector is disposed substantially vertically below a predetermined position.

The invention concerns an apparatus for scanning the optical properties of materials using a stationary sample stage and a dual-axis rotational system. The apparatus includes motors for azimuthal and polar rotation, supporting an optical system with adjustable lenses and filters to collect data from multiple angles. This design is particularly advantageous for photo-excited materials using linearly polarized sources, as it maintains static pump polarization, eliminating the need for additional motors or optical elements to align the pump with the sample's rotation. This avoids complications with halfwave plates and broadband retarders, which may not preserve linear polarization across all wavelengths. The modular system accommodates various detectors, ensuring versatility while enabling precise, high-resolution spectral imaging. The stationary sample stage prevents alignment issues and distortion, providing consistent and accurate measurements of materials' optical properties across a range of experimental setups.
