Am SE305-PX-DK Binocular Stereo Micro, WF5x and WF10x Eyepieces, 5X/10X/15X/30X Magnification, 1X and 3X Objectives, Upper and Lower Halogen Lighting, Reversible Black/White Stage Plate, Pillar Stand, 120V, Includes Darkfield Condenser

The Am SE305-PX-DK stereo micro has interchangeable pairs of 5x18mm and 10x18mm widefield eyepieces, 1x and 3x objectives, upper and lower halogen lighting, two stage plates, a darkfield condenser, and a pillar stand. The binocular viewing head has an interpupillary range of 55 to 75mm and a 45-degree inclination to ease viewing for young users. The WF5x18mm and WF10x18mm eyepieces combine with the 1x and 3x objectives to provide 5x, 10x, 15x, and 30x magnification, and a longer working distance for inspecting large-scale specimens that require handling or repair. The optical glass lenses provide sharp images, and are fully coated to ensure high-resolution images. Dioptric adjustment accommodates individual eye-strength differences, and eye guards ensure comfortable viewing. A stereo micro, sometimes called an inspection or dissection micro, has low magnification and a long working distance that enables users to manipulate the object being inspected. The micro has upper (episcopic) illumination that reflects light off the specimen for enhanced visibility of opaque specimens, and lower (diascopic) Brightfield/Darkfield (BF/DF) 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, and Darkfield (DF) illumination reflects light off the specimen, resulting in a light image on a dark background. The 10W halogen light source provides bright light in a concentrated path. The pillar-style stand secures the head for precise focusing, and bilateral coarse focus eases use for left- and right-handed users. The stage has a frosted stage plate for use with lower (transmitted) lighting, and a reversible black and white stage plate that provides contrast with light- and dark-colored specimens when used with upper (reflected) lighting. Stage clips that secure the specimen during viewing. The micro has a 2-1/8" (53mm) working distance. All metal construction is durable and stain-resistant.

Types include compound, stereo, or digital. Compound micros use a compound optical system with an objective lens and an eyepiece. Stereo micros show object depth in a three-dimensional image. Digital micros are used to display an image on a monitor, rather than looking through a lens. Micros 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. Micros 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. Micros are widely used in education, lab research, biology, metallurgy, engineering, chemistry, manufacturing, and in the medical, forensic science, and veterinary industries. United manufactures microscopy equipment and accessories under the brand name Am. The company, founded in 1996, is headquartered in Irvine, CA.

• Stereo micro for home or classroom use enables students and hobbyists to inspect biological specimens, rocks, stamps, jewelry, and large specimens that require handing or manipulation.
• Binocular viewing head with interchangeable pairs of 5x and 10x widefield eyepieces, adjustable interpupillary distance, and 45-degree inclination to simplify viewing for young users.
• Interchangeable 1x and 3x objectives provide low magnification and longer focal length for inspecting large-scale specimens.
• Upper and lower illumination has 10W halogen light source to illuminate specimens from above, and a darkfield condenser reflects light off the specimen, resulting in a light image on a dark background.
• Frosted plate allows light to pass through from below with transparent specimens, reversible black and white stage plate provides contrast with light- and dark-colored specimens, and stage clips secure the specimen during viewing.
