Machine Vision Lenses
Jan 2009
Edmund Optics Inc.Request Info
BARRINGTON, N.J., Jan. 26, 2009 – Edmund Optics has unveiled the TechSpec compact, fixed-focal-length lenses. Designed for machine vision applications, they are optically designed for the specific working distance and resolution requirements of factory automation, inspection and qualification.

Edmund-Optics-TechSpec.jpgThe lenses feature large maximum apertures and can be used in conditions where lighting is restricted. Each one includes a broadband antireflection coating, which the company says increases transmission by up to 12 percent over standard MgF2 coatings.

Available in focal lengths of 8.5, 12, 16, 25 and 35 mm, the lenses support up to 2/3-in. sensors. They feature a locking iris and include a focus adjustment with recessed set screws to prevent unintentional adjustments. They are packaged in a compact, rugged housing to afford the user greater flexibility in space-constrained applications. Each lens is manufactured to a high tolerance, resulting in good imaging performance and minimal lens-to-lens variation, ensuring easy installation into multiple systems.

antireflection coating
A thin layer of material applied to a lens surface to reduce the amount of reflected energy. Ideally the index of refraction of that material should be equal to the square root of the product of the indices of the material on either side of the coating, while the ideal thickness for a single-layer coating is one-quarter of the wavelength at which reflectance is to be minimized. See also multilayer coating.
The technology of generating and harnessing light and other forms of radiant energy whose quantum unit is the photon. The science includes light emission, transmission, deflection, amplification and detection by optical components and instruments, lasers and other light sources, fiber optics, electro-optical instrumentation, related hardware and electronics, and sophisticated systems. The range of applications of photonics extends from energy generation to detection to communications and...
