The KBC046AR.18 Bi-Concave Lens is a 1000 to 1550 nm anti-reflection coated, 25.4 mm diameter, N-BK7 Bi-concave lens with an effective focal length of -25 mm. It is designed to meet the demanding requirements of laser electro-optic applications. Newport's N-BK7 precision bi-concave lenses are manufactured from fine annealed optical glass and are polished to tight tolerances using master test plates to ensure minimum wavefront distortion.


KBC046AR。18双凹透镜为1000 ~ 1550nm涂膜,直径25.4 mm,有效焦距- 25mm的N-BK7双凹透镜。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精密双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。
