The C & A Scientific Premiere SMP-24L binocular stereo microscope has 10x widefield eyepieces, a fixed 45-degree angle viewing inclination, 2x and 4x objectives with 20x and 40x total optical magnification, upper and lower LED lighting, a fixed stage with dual focusing knobs on rack-and-pinion mount, a frosted 95mm glass plate with clips for holding samples, and a reversible (black/white) stage plate. The binocular viewing head has a pair of eyepieces, fixed inclination to reduce eye and neck strain, eye shields to block ambient light, and rotation capability to provide a more comprehensive view and enable sharing. The objectives are mounted on a turret to ease magnification changes. The objectives provide low magnification and a longer focal length for inspecting large-scale specimens, or specimens that require hands-on manipulation or repair, including rocks, minerals, watches, or circuit boards. The microscope has upper (episcopic) illumination that reflects light off the specimen for enhanced visibility of opaque specimens, and lower (diascopic) illumination that transmits light up through the specimen for enhanced visibility of translucent and transparent objects. The LED light source provides bright, cool light for working with temperature-sensitive or live specimens. There is a three-way switch for light sources. The frosted glass stage plate allows light to pass through from below. The reversible black and white stage plate is used with top-mounted (episcopic) lighting to provide contrast with light- and dark-colored specimens. The fixed stage has stage clips to secure the slide or specimen in place while viewing. Dual knobs on a rack-and-pinion mount provide precise focus. A stereo microscope, sometimes called an inspection or dissection microscope, has a longer working distance that enables users to manipulate the object being inspected, and is used in semiconductor and electronics industries or by mineralogists, dentists, and student
