The KPX046AR.18 is a Plano-Convex Lens, a type of spherical lens, sourced from MKS/Newport. This lens, with a diameter of 12.7 mm, is designed for use in the infrared spectrum, specifically between 1000nm and 1550nm.
The lens features a plano-convex geometry, meaning one side is flat (plano) and the other is curved (convex). The curvature of the convex side is defined by a radius of 19.69 mm. The lens has a thickness of 3 mm at the edge and 4.052 mm at the center, providing a base focal length of 38.1 mm.
The KPX046AR.18 is made from N-BK7 Schott, a popular optical glass due to its excellent optical properties and relatively low cost. The lens is coated with New AR-18, a broadband anti-reflective coating, on both the front and back surfaces. This coating enhances the lens's performance by reducing reflection and increasing transmission in the infrared spectrum.
The lens is currently in stock and available for purchase on the MKS/Newport website. For more detailed information and specifications, please refer to the provided weblink.
