AmScope SM-1BSW2-L6W Professional Binocular Stereo Zoom Microscope, WH10x Eyepieces, 3.5X-225X Magnification, 0.7X-4.5X

The AmScope SM-1BSW2-L6W professional stereo zoom microscope has interchangeable pairs of 10x and 25x super-widefield high eyepoint eyepieces, a 0.7x-4.5x zoom objective, and a pillar stand. The microscope has an overall magnification range of 3.5x-225x. The binocular 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 WH10x20mm and WH25x9mm super-widefield high-eyepoint eyepieces combine with the 0.7x-4.5x zoom objective to provide 7x-112.5x zoom magnification and a longer working distance for inspecting large-scale specimens that require handling or repair. The microscope includes 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 objectives 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 6W LED light has two flexible gooseneck lights to provide bright, cool light for working with temperature-sensitive or live specimens, and a rheostat controls the amount of light emanating from the lamp. Each gooseneck is 23-1/4 (590mm). The light uses a 85V-265V power supply. The table stand has a reversible black and white stage plate that provides contrast with light- and dark-colored specimens, and stage clips to secure the specimen in place. The stage plate has a 3-3/4 diameter (95mm). The stand is 10 x 7-7/8 x 10-3/4 inches/254 x 200 x 275mm (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.
