The compound microscope features an optical system for simultaneously observing images through eyepieces and an adjustable trinocular port. The compound microscopy includes a 45 degree inclined 360 degree swiveling trinocular head, body frame, revolving quadruple nosepiece, a pair of widefield eyepieces WF10X/18, four DIN achromatic objectives: 4X, 10X, 40X (spring), 100X (spring,oil), large double layer mechanical stage, Abbe NA1.25 condenser with iris diaphragm and a LED illumination system. The LED lamp can be replaced by yourself. The trinocular port is easy to mount photo or video capability. You can add advanced accessories including darkfield condenser and phase contrast kit to upgrade your microscope. All lenses are made of high quality optical glass. The high resolution image in the field of view is crystal clear and will satisfy the demands of professionals. This trinocular microscopy is good for teaching, demonstration, clinical examination and research purpose.
