Product Description

The Ample Scientific SM-Plus-24 stereo microscope has binocular viewing heads, 30 LED bulbs for reflected and transmitted illumination, widefield 10XD eyepieces with a field number (FN) of 20 mm, and 2X and 4X objectives for total magnification of 20X and 40X. This microscope, with its stereo optical system creates a three-dimensional image, and enhances the resolution of an object or image. It is commonly used by hobbyists, educators, and professionals for research.

This microscope features binocular viewing heads set at a 45-degree degree inclination for ergonomic comfort, which ease eye strain and provide a more comprehensive view. It has 55-75 mm interpupillary adjustment for individual eye spacing.. Upper LED illumination reflects light off of the specimen, and lower LED illumination transmits light up through the specimen for enhanced visibility. Upper and lower illumination components are adjustable. The microscope has a dove-tail stand for durability that allows for one-handed operation. An ergonomic handle makes moving the microscope in a classroom or laboratory safe and secure. Stage clips hold the specimen in place.

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 viewing abilities. A trinocular eyepiece is used to output digital images or video to an internal or external device such as a camera or monitor. 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 use 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.

Ample Scientific LLC manufactures laboratory equipment and supplies such as microscopes and centrifuges. Founded in 2009, and headquartered in Norcross, GA, Ample Scientific offers scientific equipment for research, educational, clinical and industrial applications.
