The 631079-117 DURALENS™ coated Meniscus Infrared Lens is made of ZnSe material and is Bystronic® OEM compatible. It has a diameter of 1.5 in. (38.1 mm), edge thickness of 9 mm, and a focal length of 5.0 in. Zinc Selenides low absorption coefficient makes it a perfect candidate for focusing applications using high power CO2 lasers. They 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.
