Meniscus Lens, Duralens, 2.0 in. Diameter, 7.5 in. FL, 9.65 mm Edge, LVD

The 60698-117 meniscus infrared lens is made of ZnSe material and is LVD® OEM compatible. It has a diameter of 2.0 in. (50.8 mm), edge thickness of 9.65 mm, and a focal length of 7.5 in. Zinc Selenide's low absorption coefficient makes it a perfect candidate for focusing applications using high power CO2 lasers. The DURALENS™ AR coating used for these CO₂ laser lenses is designed specifically for 10.6 micron wavelength. The high quality coating increases the amount of energy going through the lens and decrease the absoption to <0.20%. These lenses are designed for high durability and accuracy and manufactured by automated CNC technology to assure complete uniformity. In most laser cutting machines, meniscus lenses are used because they produce a smaller focus diameter.
