Corning Vycor® 7921 UV-Blocking Neodymium Blue Glass

Absorbs yellow and UV wavelengths through a process that introduces neodymium and cerium to the glass. Because the elements that create higher color temperature and UV blocking are a art of the glass structure, a lamp can be produced without substantial loss of visible light transmission as seen with coated bulbs. It can be run in high temperature lamp manufacturing processes without additional cost or process steps.Special Features:Superior optical qualityTight dimensional controlThermal and chemical properties ideally suited to high temperatures.Excellent thermal shock resistanceInformation provided by Corning Incorporated.
