Magnifiers are inspection instruments that are used to magnify a product or part detail via a lens system. Magnifiers are inspection or assembly instruments that enlarge the image of a product or feature. The level of magnification (generally less... Search by Specification | Learn More about Magnifiers

...images of objects. There are two basic types of devices. Stereomicroscopes use two light paths for three-dimensional (3D) viewing. They provide high depth perception, low resolution, and low magnification. Some devices include a built-in light source... Search by Specification | Learn More about Optical and Light Microscopes

...and are available in 5X, 10X, 15X, and 20X designations. Wide field eyepieces have a larger diameter and a wider field of view. Microscope lenses and microscope objectives are used with various types of optical filters. Color filters include a wide range... Learn More about Microscope Lenses and Objectives

Specialty microscopes are designed for specific applications such as metallurgy or gemology. They use specialized techniques or technologies such as acoustics to produce magnification. Search by Specification | Learn More about Specialty Microscopes

Fresnel lenses resemble a planoconvex or planoconcave lens that is cut into narrow rings and flattened. If the steps are narrow, the surface of each step is generally made conical and not spherical. Search by Specification | Learn More about Fresnel Lenses

...scattered or secondary emission of the specimen where the probe strikes it. The magnification is controlled by the length or area scanned. Transmission electron microscopes (TEM) pass image-forming rays through the specimen being observed. Contrast... Search by Specification | Learn More about Electron Microscopes

...to view objects through a standard eyepiece. Others provide a computer interface that displays images on a monitor. Image analysis processing software allows adjustments to both linear dimensions and resolution. Total magnification, the ratio...

...in specifying metallurgical microscopes include total magnification and resolution. Total magnification is a ratio of the size of an image to its corresponding object. This is usually determined by linear measurement. Resolution is the fineness of detail... Search by Specification | Learn More about Metallurgical Microscopes

...magnification, and optical format. Focal length is the distance from the optical center of the lens to the image sensor plane. There are two types of adjustability: fixed focal length and variable focal length. A video camera’s focal ratio or F-number...
