The trinocular compound LED microscope provides both brightfield and darkfield microscope system. It offers eight level magnifications from 40X to 2000X. The darkfield microscope comes with trinocular head, body frame, reversed nosepiece, two pairs of widefield eyepieces, four DIN achromatic objectives, large double layer mechanical stage, 3W LED bright variable illumination (brighter than 30W halogen light) and darkfield NA0.7-0.9 & brightfield Abbe NA1.25 condensers. It has the par-focal (also called simul-focal) function which means the image is focused through both eyepieces and the photo tube and no view switching is needed. The LED lamp can be replaced by youself. 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 compound microscopy is ideal for professionals and also affordable for students.
