The AmScope M150C-PS25 monocular compound microscope has interchangeable 10x widefield and 25x widefield eyepieces, a forward-facing nosepiece with three DIN achromatic objectives, LED illumination, a 0.65 NA single-lens condenser, coaxial coarse and fine focus, and a plain stage. The forward-facing revolving nosepiece has 4x, 10x, and 40x DIN achromatic full-glass objectives that provide high-resolution color-corrected images. The monocular viewing head holds WF10x or WF25x eyepiece on a fixed 45-degree vertical inclination to reduce eye and neck strain and has 360-degree rotation capability to provide a more comprehensive view and enable sharing. A compound microscope is used for inspection and dissection of specimens when two-dimensional images are desired. The microscope has lower (diascopic) Brightfield illumination that transmits light up through the specimen for enhanced visibility of translucent and transparent objects. Brightfield (BF) illumination allows the specimen to absorb light, resulting in a dark image on a light background. LED illumination provides bright, cool light for working with temperature-sensitive or live specimens. The 0.65 NA single-lens condenser and disc diaphragm control the amount of light illuminating the specimen. The plain stage is 3-1/2 x 3-1/2 inches and has an opening for light transmission and stage clips to secure the slide or specimen in place while viewing. A stage stop prevents the stage or specimen from coming into contact with the objectives. Coaxial coarse and fine focus knobs are nested to speed focusing for left-and right-handed viewers. Some microscopes come with a set of 25 prepared slides of a variety of plants, animals, and minerals.
