The AmScope SM-3TZZ-54S professional stereo zoom microscope has interchangeable pairs of 10x and 20x super-widefield high-eyepoint eyepieces, a 0.7x-4.5x zoom objective, and a single-arm boom stand. The microscope has an overall magnification range of 3.5x-180x. 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 (camera sold separately). The WH10x20mm and WH20x10mm 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 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 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 microscope has a 17" pillar that has an 8" vertical working distance. The 16" single-arm boom has a 24" overall length. Bilateral focus eases use for left- and right-handed users. The microscope head can be rotated on the X- and Y-axes. The solid cast-steel base is 1-3/4 x 9 x 9 inches (H x W x D, where H is height, the vertical distance from the lowest to highest point; W is width, the horizontal distance from left to right; D is depth, the horizontal distance from front to back).

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.

is it worth the money ? i say yesmy first task was using it to repair my 500 MHZ tektronix oscilloscope,with out it,i would of probably used my 10X magnify glass, and suffered.i had approximately 50 Smd capacitors i had to remove and re-solder new ones, since some of them leaked out on the data acquisition board, causing it to fail the self test.these capacitor are very small , plus i had to inspect the board for any signs of oxidation from the electrolytic capacitors that leaked out.and i did find a lot of oxidation which i had to clean,and clean, i re-solder new capacitor, and FINALLY i FIXED IT ! ! !this scope provide a good working distance, i am not a big fan with the LED lighting, i used flu resent light,it's way betterthe only issue i found is,,,, since its single arm, every time i try to move the binocular back or forward, there is a knob on the side once you loose in it, the whole binocular tend to twice sideways due to the wight of it.double arm microscope will be way better .so i returned it, and order same spec double arm.NOTE ! ! !order it from Amazon store , i don't recommend ordering it from amscop they will give you hell if you want to return it, the customer service is rude, and dont like to deal with any returns, plus you have 14 days ONLY,,,, be aware.Amazon in the other hand way way better, i rather pay little more and order for them , then dealing with these customer service crap.will update with pictures when possible,.

Easy to assemble and makes soldering on cellphone boards a breeze.

Love the price, the quality, and the range of lenses that come with this scope. The LED light ring could be a little brighter for some circumstances but definitely not bad.
