The LBTEK Optical Microscopy Teaching System kit includes components, software, and teaching materials, covering optical properties, imaging techniques, and microscope design, making it suitable for all undergraduate courses on optical microscopy systems. In the course, students can learn how to set up optical rails, construct a Köhler illumination system, and assemble and operate a modular microscope system, thereby studying and becoming familiar with concepts such as Abbe theory, modulation transfer function, resolution, and imaging. The course also introduces several types of imaging techniques: phase contrast imaging, dark-field imaging, and fluorescence imaging. This optical microscopy teaching system can be applied in scientific research, education (teaching, demonstrations, academic exchanges), biology (observing the internal structures of tissue cells), medicine (examining and diagnosing pathological specimens), and materials science (studying tiny crystal and particle structures).
