40x magnification, NA=0.75, working distance 0.66mm, flat field semi-apochromatic correction, air medium, with spring protection (to prevent lens-sample collision), compatible with 0.17mm cover glass.

Applications:
Suitable for fluorescence observation of submicron structures (such as the fine distribution of organelles, protein localization), or brightfield/fluorescence research on precision biological samples (such as neuronal synapses). The spring design enhances operational safety.
