They can also utilize LED, fluorescent, and mirror light sources to help control viewing capabilities. Compound microscopes use a compound optical system with an objective lens and an eyepiece. Trinocular viewing head with pair of 10x super-widefield eyepieces, adjustable interpupillary distance, fixed 45-degree vertical inclination to reduce eye and neck strain, and 360-degree rotation capability to enable sharing 0.7x-4.5x zoom objective provides continuous zoom magnification and longer focal length for inspecting large-scale specimens, and a 0.5x Barlow lens extends the working distance Microscopes can have monocular (one), binocular (two), or trinocular (three) eyepieces, with varying magnification abilities. The microscope has an overall magnification range of 3.5x-45x. Microscopes can control magnification through a fixed focus, or through a range of adjustments. The vertical trinocular port can be used as a C-Mount or 23mm photo port (camera sold separately).

Eye guards, one pair Instructions AmScope SM 1TS 144S 5M Digital Professional Trinocular A Barlow lens with a magnification of less than 1.0 reduces magnification and increases the working distance. The company, founded in 1996, is headquartered in Irvine, CA. Stereo microscopes show object depth in a three-dimensional image. 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. It has a 2-3/8 inner diameter and uses a 110V-120V power supply. Microscopes are widely used in education, lab research, biology, metallurgy, engineering, chemistry, manufacturing, and in the medical, forensic science, and veterinary industries. The microscope comes with a 0.5x Barlow lens that can be added to the objective to decrease the magnification range. The interaction between field of view (FOV), numerical aperture (NA), and working distance (WD) determines resolution. 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.
