RX 50 Series characteristics:

• Infinity color corrected optical system, new upgraded Koehler illuminator 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 function, 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.
