The AmScope SE303-PZ elementary stereo microscope has interchangeable pairs of 10x18mm and 20x10mm widefield eyepieces, 1x and 3x objectives, tungsten lighting, and a reversible black and white stage plate. The 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 illumination. The 10W tungsten (incandescent) light source provides bright light. 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 reversible black and white stage plate that provides contrast with light- and dark-colored specimens, and stage clips that secure the specimen during viewing. The microscope has a 3-3/16″ (81mm) 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 AmScope SM-6TZ-54S-9M digital professional trinocular stereo zoom microscope has a pair of 10x super-widefield high-eyepoint eyepieces, a 0.7x-4.5x zoom objective, two Barlow lenses, and a clamping articulating arm stand. The microscope has an overall magnification range of 3.5x-90x. The 9MP camera has a CMOS color sensor, a reduction lens, image capture and editing software, and USB 2.0 output to capture or display still or video images on a computer or projector. The trinocular viewing head has an interpupillary range of 55 to 75mm, a 45-degree inclination to reduce eye and neck strain, and 360-degree rotation to enable sharing. The vertical trinocular port can be used as a C-Mount or 23mm photo port. The WH10x20mm super-widefield high-eyepoint eyepieces combine with the 0.7x-4.5x zoom objective to provide continuous zoom magnification and a longer working distance for inspecting large-scale specimens that require handling or repair. The microscope comes with 0.5x and 2.0x Barlow lenses that can be added to the objective to increase the magnification range. A Barlow lens with a magnification of less than 1.0 reduces magnification and increases the working distance, while a Barlow lens with a magnification greater than 1.0 increases the magnification and reduces the working distance. High-eyepoint eyepieces ease viewing for users who wear glasses, and dioptric adjustment accommodates individual eye-strength differences. A digital 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, and is used where image capture, detailed records, or documentation is required.

The 9MP digital camera has a CMOS color sensor for displaying still microscopy images and streaming live videos to a computer or projector. The camera has 40x magnification and a 0.5x reduction lens that ensures that the display has a similar field of view as the microscope eyepiece. The camera can be mounted in a C-Mount or any 23mm eye tube. The camera includes image capture and editing software that provides still image and live video capture and editing capability, including measurement functions. The software supports JPG, TIF, GIF, PSD, WMF, and BMP file formats and is compatible with Windows XP, Vista, 7, and 8; Mac OS X; and Linux. Camera drivers are compatible with Windows XP, Vista, 7, and 8; Mac OS X; and Linux. The software includes Windows APIs for native C/C++, C#, DirectShow, Twain, and LabVIEW that enable custom application development. The camera has a USB 2.0 data port (cable included).

The removable 54-bulb LED ring light provides bright, cool light for working with temperature-sensitive or live specimens. The ring light provides shadow-free illumination, and a rheostat controls the amount of light emanating from the lamp. Power and adjustment controls are located on the light head. The light uses a 110V-240V variable power supply. The stand has an articulating arm with a 40″ reach for covering a large work space, and a clamp for attaching the microscope to a work surface. The stand can be attached to ledges up to 2-1/8″ (53mm) thick.
