The trinocular compound LED microscope provides both brightfield and darkfield microscope system. It offers eight level magnifications from 40X to 2000X. The darkfield biological microscope features an optical system for simultaneously observing images through eyepieces and an adjustable trinocular port. The laboratory microscopy comes with trinocular head, body frame, revolving quadruple nosepiece, two pairs of widefield eyepieces, four DIN achromatic objectives, large double layer mechanicalstage, LED illumination system and darkfield NA0.7-0.9 & brightfield Abbe NA1.25 condensers. The LED lamp can be replaced by yourself. 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.
