GCI uses the most advanced microscopic noise-free lighting environment which features dark field and bright
field illumination, variable intensity control and has stable illumination with strategically designed illumination ports. They are
adjustable for diopter differences in vision and feature more variable functions. All the stereo microscope bodies are equipped with
adjustable diopter tubes. This system is equipped with a laser system which enhances the performance of various gemological examinations.
It is these characteristics which enables focusing in areas, portions or microscopic inclusions.
