The BestScope BLM-340 Digital Stereo Zoom Microscope with 9″ TFT LCD has a 0.7x to 4.5x zoom objective for 9x to 80x continuous magnification, a 1x auxiliary objective, upper LED illumination, a fixed stage, and an SD card. The 5.0MP digital camera displays images on the built-in TFT (thin film transistor) LCD screen or on a monitor or projector (sold one after the other). Images can also be displayed in color, black and white, or negative mode. The zoom objective provides low magnification and a longer focal length for inspecting large-scale specimens, or specimens that require hands-on manipulation or repair, including rocks, minerals, watches, or circuit boards. A digital stereo zoom microscope provides zoom magnification that allows the user to zoom in on the specimen within a continuous magnification range. It is used for inspection and dissection when three-dimensional images are desired, and where image capture, detailed records, or documentation is required.
The digital camera has a CMOS color sensor for displaying still microscopy images and streaming live videos to the LCD screen or to a monitor or projector. The camera has an HDMI data port. Images can also be stored on the included SD card.
The microscope has an LED ring light for upper (episcopic) illumination that reflects light off the specimen for enhanced visibility of opaque specimens. The LED light source provides bright, cool light for working with temperature-sensitive or live specimens, and offers selectable four-zone lighting with brightness keep an eye on.

Microscopes are instruments used to improve 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, fairly than having a look through a lens. Microscopes can have monocular (one), binocular (two), or trinocular (three) eyepieces, with varying magnification abilities. Magnification ability refers back to the size of an image. Resolution, often referred to as resolvant power, refers back to the clarity of the image. The interaction between field of view (FOV), numerical aperture (NA), and working distance (WD) determines resolution. Microscopes can keep an eye on magnification through a fixed focal point, or through a range of adjustments. They are able to also utilize LED, fluorescent, and mirror light sources to help keep an eye on viewing capabilities. Microscopes are widely used in education, lab research, biology, metallurgy, engineering, chemistry, manufacturing, and in the medical, forensic science, and veterinary industries.
BestScope International Ltd. manufactures microscopes, digital cameras, and accessories for education, inspection, research, and clinical and industrial applications. The company, founded in 1995, is headquartered in Beijing, China.
