It is ideal for viewing cell tissues, bacteria, and fungi in both self-prepared slides and pre-made-slides, such as onion cells, leaf cells, cheese bacteria, etc. It makes the microscopic world within the reach to everyone. Built to Last AmScope M100C-LED comes with all glass optical elements and solid metal body. The microscope provides sharp clear images and will last long enough to cover all the way from elementary to high school. The sturdy metal construct offers stable images at high magnification levels instead of shaking ones. The build-in battery slot uses three AA batteries to power the microscope on-the-go, and an 110V-4.5V transformer can be plugged in when using indoor setting. Excellent Optics AmScope M100C-LED features five levels of magnification settings that produce crystal clear image without any frustrations. Glass achromatic objectives minimizes aberration and last longer. About Microscopes 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. AmScope has been manufacturing microscopy equipment and accessories since 1996, headquartering in Irvine, CA. Packing List: A great portable LED microscope!
