An LED bulb provides high intensity low temperature illumination to your microscope every aspect of which can be controlled by the 1.25 NA Abbe condenser on the G380M which uses a rack and pinion design to adjust the light spread on your sample. Huge coaxial coarse and fine focusing knobs are located on either side of the microscope and UNICO has equipped each knob with tension adjustment to eliminate drifting of the mechanical stage. All of these features are packed into a sturdy cast metal frame complete with a blue polymer access panel.
