...image. They typically employ color separation devices such as beamsplitters rather than having integral filters on the sensors. Choices for imaging technologies for video cameras include CCD, CMOS, tube, and film. Charge Coupled Devices (CCD) use... 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

...speed cameras include CCD, CMOS, tube, and film. Charge Coupled Devices (CCD) use a light-sensitive material on a silicon chip to detect electrons excited by incoming light. They also contain integrated microcircuitry required to transfer the detected... Search by Specification | 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

Magnifiers are inspection instruments that are used to magnify a product or part detail via a lens system. Search by Specification | Learn More

...are used for color balancing, matching CCD or other sensor sensitivity ranges, emphasizing or blocking ranges of spectra such as ultraviolet, infrared, or portions of the visible spectrum (colors). Camera filters are available in many styles include... Search by Specification | Learn More

Complementary metal oxide semiconductor (CMOS) cameras use image sensors that operate at lower voltages than charged coupled devices (CCDs), reducing power consumption for portable applications. Each CMOS active pixel sensor cell has its own buffer amplifier, and can be addressed and read individually. 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

...micro achromats as well. Achromats consist of two or more lenses, which must be fixed in relation to one another by either mounting or cement. They are a very common type of viewer lens. Achromats of two or three lens elements (referred... 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
