In continuation of the Philips line of collimation lenses for laser diodes, Penta ht optics manufactures the famous CAY033/40, CAY046/74, CAY046/55 and CAW100. With or without Anti-Reflex coating.
Types and Specification
Since 1985, in Philips plastic aspherical collimating lenses have been manufactured, primarily for use in CD and later DVD and BluRay optical storage systems. From these lenses general purpose collimation lenses for laser diode have been derived. In this way, users of these lenses benefit of the well designed and rigorous quality approach needed for a mass manufactured product. Because of the High Quality / Low Cost necessity, the manufacturing method of choice has been injection molding of optical plastic in high precision molds with optical finish. With this approach an exceptionally high degree of uniformity is created between lenses of one delivery batch.
Over time, many millions of these lenses have found there way to the respective users, in Optical Storage industries, Barcode scanning, Laser pointing and many other applications. Since 2002, the manufacturing lines for these lenses were relocated to Suzhou, China, where Philips established a plant for optical components and devices. From 2008 Penta ht optics is selling these lenses worldwide.
