The KPC040AR.18 N-BK7 Plano-Concave Lens is a 1000 to 1550 nm anti-reflection coated, 25.4 mm diameter, N-BK7, plano-concave lens with an effective focal length of -50 mm. It is designed to meet the demanding requirements of laser electro-optic applications. Newport's N-BK7 precision plano-concave lenses are manufactured from fine annealed optical glass and are polished to tight tolerances using master test plates to ensure minimum wavefront distortion.


KPC040AR。18n - bk7平凹透镜是一种涂有1000 ~ 1550nm的防反射涂层,直径25.4 mm, N-BK7,有效焦距- 50mm的平凹透镜。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精密平凹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。
