The BestScope BPM-620 Portable Handheld Metallurgical Microscope has a 10x plan eyepiece, 10x and 50x long working-distance plan metallurgical objectives, and vertical LED illumination. Plan eyepiece and objectives provide improved focus over the entire field of view (FOV). The longer working distance of the objectives enables inspecting raw materials and viewing specimens in dishes and large containers. Vertical LED illumination reflects light off the specimen for enhanced visibility of opaque specimens, and is adjustable for brightness control. Metal construction provides durability. A metallurgical microscope uses transmitted and reflected light to view opaque or metallurgical specimens, or larger specimens that cannot be viewed on a standard microscope stage.

H is height, the vertical distance from the lowest to highest point; W is width, the horizontal distance from left to right; D is depth, the horizontal distance from front to back.
Microscopes are instruments used to enhance the resolution of an object or image. Types include compound, stereo, or digital. Compound microscopes use a compound optical system with an objective lens and an eyepiece. Stereo microscopes show object depth in a three-dimensional image. Digital microscopes are used to display an image on a monitor, rather than looking through a lens. Microscopes can have monocular (one), binocular (two), or trinocular (three) eyepieces, with varying magnification abilities. Magnification ability refers to the size of an image. Resolution, also known as resolvant power, refers to the clarity of the image. The interaction between field of view (FOV), numerical aperture (NA), and working distance (WD) determines resolution. Microscopes can control magnification through a fixed focus, or through a range of adjustments. They can also utilize LED, fluorescent, and mirror light sources to help control viewing capabilities. Microscopes are widely used in education, lab research, biology, metallurgy, engineering, chemistry, manufacturing, and in the medical, forensic science, and veterinary industries.
