The KBX157AR.18 N-BK7 Bi-Convex Lens is a 2 inch (50.8 mm) diameter, 1000 to 1550 nm anti-reflection coated, N-BK7 bi-convex lens with an effective focal length of 125 mm. It is designed to meet the demanding requirements of laser electro-optic applications. Newport's N-BK7 precision bi-convex lenses are manufactured from fine annealed optical glass and are polished to tight tolerances using master test plates to ensure minimum wavefront distortion.


KBX157AR。18n - bk7双凸透镜直径2英寸(50.8 mm),涂有1000 ~ 1550nm的防反射涂层,有效焦距125mm,为N-BK7双凸透镜。它是为满足激光电光应用的要求而设计的。纽波特公司的N-BK7精密双凸透镜是由经过精细退火的光学玻璃制造的,并使用主测试板抛光至严格公差,以确保最小的波前畸变。
