BestScope BS-2000B Basic Monocular Compound Microscope, 5x, 10x, and 16x Eyepieces, 50x-640x Magnification, Brightfield, Mirror Illumination, Iris Diaphragm, Plain Stage
The BestScope BS-2000B Basic Monocular Compound Microscope has 5x, 10x, and 16x eyepieces, a forward-facing nosepiece with two achromatic objectives, mirror illumination, separate coarse and fine focus, an iris diaphragm, and a plain stage with stage clips. Achromatic objectives provide color correction of magnified images. A forward-facing nosepiece eases changing objectives. A basic compound microscope is used in classroom, home school, and hobbyist settings for inspection and dissection of specimens when two-dimensional images are desired. 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. A mirror directs light onto the specimen without the need for power or batteries, and an iris diaphragm optimizes the amount of light illuminating the specimen. The plain stage has an opening for light transmission, and stage clips to secure the slide or specimen in place while viewing. Separate coarse and fine focus knobs speed focusing.
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?
