| This unit functions as a microspectroscopy microscope that combines microscopic observation with microspectroscopic measurement, and is an optical unit for precisely measuring emission spectra from micro-areas. While observing the sample surface under a high-magnification microscope, the user can accurately target any small spot within the field of view and efficiently acquire emission, fluorescence, or photoluminescence (PL) spectra from that localized area. Weak light collected through the objective lens is guided to an optical fiber or spectrometer, enabling highly sensitive spectral analysis with high spatial resolution. The unit supports a wide range of research and development applications, such as evaluating the optical properties of microstructures, analyzing material homogeneity, and identifying the emission behavior of defect sites, and covers a broad wavelength range from ultraviolet through visible to near-infrared. Three wavelength ranges are available: ① 266 nm to 620 nm, ② 355 nm to 1064 nm, and ③ 400 nm to 2000 nm, allowing the optimum configuration to be selected for the measurement target. It can also be used as a UV microscope or a near-infrared microscope, making it ideal for evaluating the spatial distribution of optical properties. |
