...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

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

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

Magnifiers are inspection instruments that are used to magnify a product or part detail via a lens system. 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

Fresnel lenses resemble a planoconvex or planoconcave lens cut into narrow rings and flattened. If the steps are narrow, the surface of each step is generally conical and not spherical. Gradient index (GRIN) lenses focus light through a precisely... Search by Specification | Learn More
