AmScope AmScope SE305R-AZ Forward-Mounted Binocular Stereo Microscope, WF10x and WF20x Eyepieces, 10X/20X/30X/60X Magnification, 1X and 3X Objectives, Upper and Lower Halogen Light Source, Arm Stand, 120V

The AmScope SE305R-AZ stereo microscope has interchangeable pairs of 10x18mm and 20x10mmwidefield eyepieces, 1x and 3x objectives, upper and lower halogen lighting, two stage plates, and an arm stand. The forward-mount...ed binocular viewing head has an interpupillary range of 55 to 75mm and a 45-degree inclination to ease viewing for young users. The WF10x18mm and WF20x10mm eyepieces combine with the 1x and 3x objectives to provide 10x, 20x, 30x, and 60x 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 microscope, sometimes called an inspection or dissection microscope, has low magnification and a long working distance that enables users to manipulate the object being inspected.

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 10W halogen light source provides bright light in a concentrated path. 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 microscope has a 2-1/8" (53mm) working distance. All metal construction is durable and stain-resistant.

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.

The VanGuard 1100ZL Series Stereo Zoom Microscopes with either a binocular or trinocular head have a 360-degree rotation capabilit...y and a fixed 45-degree vertical inclination to ease eye strain, -5 to +5 dioptric adjustment capabilities to compensate for the difference in viewing ability between each eye, and 55 to 90mm interpupiliary adjustment for individual eye spacing. The models in this series have 20mm 10x super widefield eyepieces, lens objectives of 0.7x to 4.5x, a zoom ratio of 6.5:1, and a working distance of 93 mm. The stage plate is reversible black and white for viewing light or dark samples, and the microscope has two, locked on, stainless steel, spring-loaded stage clips for durability. The units come with either a pole stand (100 mm vertical travel) or boom stand (300 mm vertical travel x 415 mm horizontal travel). They have dual focus adjustment knobs, for controlled focusing. These microscopes have a rack and pinion assembly, a slip clutch mechanism, and a tension control mechanism to protect the gears. The trinocular head model can be connected to a camera for an alternative viewing option. They are stain-resistant and have a durable cast metal body with an enamel finish, and anti-skid rubber feet. These models come with a spare fuse, two eyecups, a dust cover, and instructions. Additional optional eyepieces, lenses, lighting, and camera packages are sold separately.
