The AmScope SM8TZ144S10M digital professional trinocular stereo zoom microscope has a pair of 10x superwidefield higheyepoint eyepieces, a 0.7x4.5x zoom objective, two Barlow lenses, and an articulatingarm clamping boom stand. The microscope has an overall magnification range of 3.5x90x. The 10MP 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 45degree inclination to reduce eye and neck strain, and 360degree rotation to enable sharing. The vertical trinocular port can be used as a CMount or 23mm photo port. The WH10x20mm superwidefield higheyepoint eyepieces combine with the 0.7x4.5x zoom objective to provide continuous zoom magnification and a longer working distance for inspecting largescale 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. Higheyepoint eyepieces ease viewing for users who wear glasses, and dioptric adjustment accommodates individual eyestrength 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 10MP 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 CMount 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 144bulb LED ring light provides bright, cool light for working with temperaturesensitive or live specimens. The ring light provides shadowfree illumination, and a rheostat controls the amount of light emanating from the lamp. Power and adjustment controls are located on the light head. The ring has a 2.4inch (61mm) inside diameter and a 4inch (100mm) outside diameter. It has a 100,000hour life span and a 110V240V variable power supply. The pillartype articulatingarm base has a 40inch reach for covering a large work space. The pillar is 24inch and the holder ring has a 3inch diameter. The stand can be secured with the clamp to the edge of a desk or table.

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 threedimensional 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)
