Product News for Fresnel Lens Array
Knight Optical Ltd.
Precision Fresnel Lenses Fresnel lenses replace the curved surface of a conventional lens with a series of concentric grooves, moulded into the surface of lightweight plastic sheets. These grooves act as individual refracting surfaces when viewed in cross section. Our large-aperture, lightweight plastic lenses are often used as collimators and collectors in sensor or communication systems. . Our precision range Fresnel lenses offer very close tolerances and a better surface finish. These properties make... (read more)Browse Optical Lenses Datasheets for Knight Optical Ltd.

Ross Optical Industries
Cylindrical Lenses A lens having at least one surface that is a portion of a cylinder. Cylindrial lenses focus light along one axis only, thus forming a line image from a parallel incident beam. Typically used in the slit illumination of apertures, or converging the light for a line scan detector as well as stretching a point of light into a line as in a laser level. Ross Optical Industries Management and Employees pledge commitment to Excellence, Conformance to Customers requirements, and Continuous Improvement...

PHOTONIS Technologies SAS
Electron Generator Arrays Because each of the millions of pores produce electrons, the resultant electron flux is extremely uniform and dense. EGAs can be used as the electron source in electron impact ionization source applications. This technology has the advantage of performing as a cold ionization source, which eliminates pyrolytic effects that occur when the heat generated by the filament chemically changes the unknown substances to be identified.
