From Manufacture

AmScope B490B high power compound microscope is designed for professional applications in clinical offices and research laboratories. This microscope comes with a 30 degree inclined 360 degree swiveling binocular compensation-free head, 3D mechanical stage, coaxial coarse fine focusing system, intensity-variable halogen illumination, and bright field condenser. It gives eight level magnifications: 40x-80x-100x-200x-400x-800x-1000x-2000x. It is a right instrument for clinical or research applications that need both phase contrast and bright field features. It is brand new in factory sealed box.

Precise Optics & Sturdy Framework

AmScope B490B microscope comes with fully coated optical system, DIN Achromatic objectives, precise ground glass lenses as well as all glass optical elements that ensure high resolution crystal clear sharp images. The microscope has a sturdy solid metal framework with stain resistant enamel finish, a large 3D double layer mechanical stage with low position coaxial controls, coaxial coarse fine focusing system, and all metal mechanical parts. The microscope comes with excellent five (5) year factory warranty.

About Microscopes

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. AmScope has been manufacturing microscopy equipment and accessories since 1996, headquartering in Irvine, CA.
