The OMAX M837S is a trinocular compound microscope that fits the needs from doctors to students at an affordable price. It comes with everything an advanced microscope should have: 3D two layer mechanical stage with highest position lock, coaxial focus knobs, focus adjustable Abbe condenser with Iris diaphragm, intensity adjustable halogen light and filters. The magnification goes up to 2000x. The trinocular port is par-focal which means that image from the optional camera and the image from the binocular head are focused at the same time. In additon, you don't have to switch the image between the photo port and the eyepieces. This microscope is good for teaching and demonstrations. It can be used for lab tests, clinical examinations, or education. A standard 23.2mm photo port for most microscope digital cameras is included. This scope is also capable to add other accessories, e.g. darkfield condenser, phase contrast condenser and lenses, thermal control stage, C-Mount port.
