BestScope BS-2020BD Digital Siedentopf Binocular Compound Microscope, WF10x Eyepieces, 40x-1000x Magnification, Brightfield, LED Illumination, Abbe Condenser, Iris Diaphragm, Mechanical Stage, 110V, Includes 1.3MP Camera with Software
The BestScope BS-2020BD Digital Siedentopf Binocular Compound Microscope has a pair of 10x widefield eyepieces, a reverse-mounted nosepiece with four achromatic objectives, LED illumination, coaxial nested coarse and fine focus, 1.2 NA Abbe condenser with iris diaphragm, and a mechanical stage. The 1.3MP camera digital camera captures and displays images on a computer or projector. The Siedentopf binocular head has a pair of eyepieces with interpupillary adjustment, and fixed inclination to reduce eye and neck strain. A Siedentopf binocular head enables the viewer to change the interpupillary distance without changing the tube length, eliminating the need to refocus the image. A reverse-mounted nosepiece keeps objectives out of the way to prevent damage and contamination, and to enable more secure slide handling. Achromatic objectives provide color correction of magnified images. A digital compound microscope is used for inspection and dissection of specimens when two-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 a computer or projector. It includes image capture and editing software that provides still image and live video capture and editing capability, including measurement functions. The software is compatible with Windows Vista, 7, and 8; and Mac OS X. The camera has a USB 2.0 output. The microscope has lower (diascopic) brightfield illumination that transmits light up through the specimen for enhanced visibility of translucent and transparent objects. Brightfield (BF) illumination allows the specimen to absorb light, resulting in a dark image on a light background. The LED light source provides bright, cool light for working with temperature-sensitive or live specimens, and a rheostat controls the amount of light emanating from the lamp. The Abbe condenser can be adjusted to control the distance of the light from the stage and has an iris diaphragm to optimize the amount of light illuminating the specimen. The mechanical stage locks the slide into place and provides precise slide manipulation along the X- and Y-axes. Coaxial coarse and fine focus knobs are nested to speed focusing for left-and right-handed viewers.
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. 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. What's in the Box?
