These compound microscopes have a 45° inclined viewing head that rotates 360°. Achromatic objectives are parfocaled, parcentered and color-coded to provide sharp, color-corrected magnified images. Brightfield LED illumination illuminates the specimen from below, making the specimen appear bright, but much darker then the bright background. A disc diaphragm controls the amount of light illuminating the specimen. The round gliding stage has an opening for light to pass through and allows for multidirectional, precise slide adjustment. The one touch stage clips secure the slide in place for viewing. Rugged metal components engineered for years of reliable performance. Includes a dust cover and instruction manual. 5-year limited warranty.
