BestScope BS-8030T Gemological Trinocular Zoom Microscope, WF10x Eyepieces, 20x-40x Magnification, Brightfield and Darkfield Illumination, Halogen and Fluorescent Light Sources, 110V

The BestScope BS-8030T Gemological Trinocular Zoom Microscope has a pair of 10x super widefield eyepieces, a 23.2mm trinocular port, a 1x-4x zoom objective, brightfield and darkfield halogen and fluorescent illumination, and a gem clamp. The trinocular viewing head has a binocular head with a fixed inclination to reduce eye and neck strain, and 360-degree rotation capability to provide a more comprehensive view and enable sharing; and a trinocular port that accepts a camera adapter (sold separately). The objective has 90.5mm working distance (WD) and 22-5.5mm field of view (FOV) for examining specimens. A gemological microscope uses transmitted and reflected light to view gemstones.

The microscope has brightfield upper (episcopic) illumination that reflects light off the specimen for enhanced visibility of opaque objects, and lower (diascopic) illumination that transmits light up through the specimen for enhanced visibility of translucent and transparent objects. It includes a darkfield attachment. Brightfield (BF) illumination allows the specimen to absorb light, resulting in a dark image on a light background, and darkfield (DF) illumination reflects light off the specimen, resulting in a light image on a dark background. The halogen upper and lower light sources provide bright light in a concentrated path. The fluorescent upper light source provides cool, white light for observing specimens as they would appear in their natural environment. A gem clamp is used to secure specimens.

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.
