BM-40 biological upright microscope

BM-40

Infinity color corrected optical system, new upgraded Koehler illumination system, presents a clear & bright micro-image under each magnification.

Fire-new ergonomic design, steady system structure, easy operation, is suitable for various working environments.

“Building blocks” design for combining multiple functions, fluorescence, phase contrast, polarizing, dark field attachments can be assembled on the basis of bright field observation.

Widely apply to clinical diagnosis, teaching experiment, pathological test and other micro-fields.
