Optical lens assemblies are composed of a number of lenses mounted for a particular imaging function. These can include objectives, collimators, gauging lenses, etc. Learn More

...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... Search by Specification | Learn More

Lens holders are used to stabilize and maintain the position of all the optical components of a lens assembly. Learn More

Optical scanners are motorized mirror mounts and system used in scanning applications. Learn More

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

...of the slide. There are many different types of microscope stages. Examples include automated, manual, motorized, rotary, and Z-axis stages. The motion and operation of an automated stage is controlled from a personal computer (PC) or other control system... Search by Specification | Learn More

Filter wheels hold and position multiple filters for various imaging applications such as machine vision and spectrophotometry. Filter wheels are used to position a selection of filters over a lens, or an array of lenses. Applications for filter... Search by Specification | Learn More

...or diverge the transmitted rays from an object, thus forming a real or virtual image of that object. There are seven main spherical lens forms, or shapes, that determine the imaging characteristics of the lens. They are plano-convex, plano-concave... Search by Specification | Learn More

Gradient index (GRIN) lenses focus light through a precisely controlled radial variation of the lens material's index of refraction from the optical axis to the edge of the lens. Search by Specification | Learn More

Cylindrical lens have at least one surface that is formed in the shape of a cylinder. Cylindrical lenses are used to correct astigmatism in the eye, and, in rangefinders, to produce astigmatism, stretching a point of light into a line Search by Specification | Learn More

...of the light beam that enters the lens. C-mounts are adapters for video cameras. Typically, the user removes the camera lens and installs the C-mount, which connects to the microscope’s trinocular port. Unlike C-mounts, T-mounts are used with still... Learn More

...to their original energy levels, they emit lower-energy and longer-wavelength light. Inverted, confocal, and polarized light microscopes are industrial microscopes. An inverted microscope locates the illumination system above the stage and the lens... Search by Specification | Learn More
