KPX178AR.18 50.8 mm Dia. x 62.9 mm FL; IR coated; Plano-Convex Lens IR 1000-1550nm
This product is a Plano-Convex Lens, specifically designed for use in the infrared spectrum, with a diameter of 50.8 mm and a focal length of 62.9 mm. The lens is sourced from MKS/Newport, a reputable vendor in the optical industry.
The lens is made from N-BK7 Schott, a popular material for optical lenses due to its excellent optical properties and wide transparency range. The lens's geometry includes a 3 mm thickness at the edge, increasing to 15.221 mm at the center, and a 32.507 mm radius of curvature on the front surface. The lens's effective focal length (EFL) is 62.9 mm, and the back focal length (BFL) is 52.86 mm.
The KPX178AR.18 lens features a new AR-18 coating on both the front and back surfaces, designed to reduce reflection and increase transmission in the infrared spectrum, specifically between 1000 and 1550 nm. This coating ensures optimal performance in IR applications.
