Description
- Stereo microscope creates three-dimensional images for use in lower magnification educational, biological, inspection and life science applications
- Binocular head that can be rotated 360-degrees to ease eye strain, with single diopter adjustment capability to compensate for different viewing between each eye
- 10x widefield eyepiece (FN20), zoom ratio of 4:1, 1.75x to 180x magnification, working distance of at least 80mm, parcentered and parfocal lens system, and Greenough optical system for precision image creation
- Models come with a boom or pole stand and certain models come with either upper/lower halogen lighting or upper halogen/lower fluorescent lighting all with dimmers for intensity control
- Rack and pinion focusing provides precise focusing with tension control adjustment and the slip-clutch mechanism prevents gear damage
The Thomas Stereo Zoom Binocular Microscope has a binocular head that can be rotated 360-degrees to ease eye strain, with single diopter adjustment capability to compensate for different viewing between each eye. This model has a 10x widefield eyepiece field number 20 (FN20), a zoom ratio of 4:1, 1.75x to 180x magnification, a working distance of at least 80mm, parcentered and parfocal lens system, and Greenough parallel optics system for crisp, flat images with brilliant contrast and exceptional depth of field. This instrument comes with a boom or pole stand and certain models come with either upper/lower halogen lighting or upper halogen/lower fluorescent lighting all with dimmers for intensity control. The rack and pinion focusing provides fluid, precise focusing ability with tension control adjustment. The slip-clutch mechanism prevents gear damage. The frosted glass stage plate in the base allows light to pass through from below and provides evenly diffused illumination. This microscope comes with a dust cover, light bulbs, and instructions. Stereo microscopes create three-dimensional images and are used for education, biological sciences, and manufacturing applications, among others.
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.
