KPX085AR.18 25.4 mm Dia. x 62.9 mm FL; IR coated; Plano-Convex Lens IR 1000-1550nm
The KPX085AR.18 is a Plano-Convex Lens, a type of spherical lens, sourced from MKS/Newport. This lens has a base shape of a circle and is designed for use in the infrared spectrum, specifically between 1000nm and 1550nm. The lens is made from N-BK7 Schott, a popular optical glass due to its excellent optical properties and relatively low cost.
The lens has a diameter of 25.4mm and a thickness at the edge of 3mm. The center thickness is 5.584mm, providing a solid structure for the lens. The effective focal length (EFL) of the lens is 62.9mm, which is the distance from the lens's center to the focal point when the lens is imaging an object at infinity.
The KPX085AR.18 features a new AR-18 coating on both the front and back surfaces. This anti-reflective coating is designed to reduce surface reflections, thereby increasing the amount of light transmitted through the lens. The inner radius of the lens is zero, indicating a flat surface on the back side.
This lens is currently in stock and more information can be found on the MKS/Newport website.
