The VanGuard 1115AML compound Brightfield educational microscope has a binocular viewing head with a fixed 45-degree inclination, 360-degree rotation capability, a magnification ability of up to 1000X, and a 1.25 NA Abbe condenser with iris diaphragm. The binocular viewing configuration has 55 to 75mm interpupillary and -5 to +5 dioptric adjustment to accommodate differences in users' eyes. This microscope, commonly used in educational and basic research applications, enhances the resolution of an object or image with its compound optical system.

This microscope features Deutsches Institut fur Normung (DIN) standard achromatic objective lenses, which correct for red and yellow chromatic aberrations. Adjustable resolution provides DIN-standard resolvant options of 4X, 10X, 40X, and 100X. The 1112AML optical system is fixed at 160mm. It has an LED brightfield illumination configuration that allows a specimen to absorb light for clear illumination, a 1.25 NA Abbe condenser for higher resolution, and an iris diaphragm to control light. A 10X widefield eyepiece magnifier locks onto the unit for ease of operation, and provides an 18mm field distortion (FD). The square, mechanical stage is chemical-resistant, and has drop-down, left-hand, rack and pinion X-Y controls. The stage has a removable, spring-clip slide holder mechanism to provide specimen maneuverability. It has coarse- and fine-control focus adjustment mechanisms, a focusing range of 40mm, and focus tension adjustment. Safety auto-stops prevent unit damage. The forward-pitch nosepiece has secure, positive stops, and four rotation positions support a range of magnification. The microscope has a stain-resistant and durable cast metal body with an enamel finish, and anti-skid rubber feet to prevent slipping. It comes with spare fuse, a dust cover, and instructions.

The 1115AML portable microscope overall dimensions are 370 x 150 x 195 mm (H x W x D, where H is height, the vertical distance from lowest to highest point; W is width, the horizontal distance from left to right; D is depth, the horizontal distance from front to back). Its base dimensions are 195 x 150 mm (W x D), and its stage is 120 x 120 mm (W x D). The stage has a cross-travel range of 60 x 25 mm, and the microscope weighs 5.0kg. It works with a 0.5 amp fuse (included) and 110V power source with integrated power cord for illumination.

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.
