For Industrial Laser Scanning
BARRINGTON, N.J., April 14, 2008 -- Edmund Optics has introduced a line of TechSpec f-Theta scanning lenses designed to optimize the laser scanning process. These lenses are optimized for use with either Nd:YAG lasers operating at 1064 nm or CO2 lasers operating at 10.6 µm.

Most commonly used in high-end laser scanning and printing applications, f-Theta lenses are also widely used for laser marking, engraving and cutting systems. In scanning systems incorporating galvanometers, the laser beam may propagate at varying angles relative to the optical axis causing distortion, Edmund Optics said. f-Theta lenses are designed to correct this distortion, providing a flat field at the image plane.

The TechSpec f-Theta scanning lenses are available at a range of focal lengths varying from 100 to more than 250 mm, which can scan fields as large as 175 x 175 mm, the company said. The Nd:YAG lens incorporates three elements with a highly efficient antireflective coating to provide optimal resolution and throughput; the CO2 lens is a single-element design. All lenses are provided with industry-standard M85 threading, which eases mounting and retrofitting on OEM equipment, the company said.

GLOSSARY
beam
1. A bundle of light rays that may be parallel, converging or diverging. 2. A concentrated, unidirectional stream of particles. 3. A concentrated, unidirectional flow of electromagnetic waves.
cutting
The process of forming a lens to a given pattern, or of cutting a piece of glass along the line of scratch.
galvanometer
An instrument for detecting or measuring small electric currents.
lens
A transparent optical component consisting of one or more pieces of optical glass with surfaces so curved (usually spherical) that they serve to converge or diverge the transmitted rays from an object, thus forming a real or virtual image of that object.
photonics
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...
scanning
The successive analysis or synthesizing of the light values or other similar characteristics of the components of a picture area, following a given method.
