The tungsten (incandescent) light sources provide bright light. Lighting can be configured for upper, lower, or simultaneous upper and lower illumination. The reversible black and white stage plate is used with top-mounted lighting to provide contrast with light- and dark-colored specimens.
The frosted glass stage plate provides evenly diffused illumination. The fixed stage has stage clips to secure the slide or specimen in place while viewing.
Coaxial focus eases focusing for left- and right-handed viewers. Focus tension control prevents stage drift, and a built-in slip clutch system prevents damage to the focus mechanism. The cast metal frame provides durability and has a gray enamel finish. Microscope Head and Optics Specifications.
Objectives, achromatic, parcentered and parfocal. Microscope Illumination and Stage Specifications. Upper and lower tungsten (incandescent), 12V/10W.
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. National Optical and Scientific Instruments manufactures microscopes and microscope cameras. The company, founded in 1991, is headquartered in Schertz, TX. What's in the Box?
National Optical 405TBL-10-2 Binocular Stereo Microscope. Reversible black/white stage plate, 80mm.Frosted glass stage plate, 80mm. Binocular head with pair of 10x widefield eyepieces with 50 to 75mm interpupillary adjustment and fixed 45-degree vertical inclination to reduce eye and neck strain. Paired 2x objectives provide low magnification and longer focal length for inspecting large-scale specimens. Upper and lower tungsten illumination with interchangeable stage plates and selectable lighting configuration for clear examination and light control. Fixed stage with clips secures slides in place, and coaxial focus knobs speed focusing and have a tension control to prevent stage drift.
