KPX211AR.18 50.8 mm Dia. x 500 mm FL; IR coated; Plano-Convex Lens IR 1000-1550nm
The KPX211AR.18 is a Plano-Convex Lens, a type of spherical lens, sourced from MKS/Newport. This lens has a diameter of 50.8 mm and a focal length of 500 mm, making it suitable for a wide range of optical applications. The lens is made from N-BK7 Schott, a popular optical glass due to its excellent optical properties and high damage threshold.
The lens features a New AR-18 coating on both the front and back surfaces. This anti-reflective coating is designed to reduce surface reflections and increase transmission in the infrared spectrum, specifically between 1000 and 1550 nm. The coating ensures high-quality performance in IR applications, making this lens an excellent choice for systems operating in this wavelength range.
The KPX211AR.18 has a thickness of 3 mm at the edge and 4.251 mm at the center. The inner radius is 0 mm, and the back focal length is 497.19 mm. The lens is available for purchase directly from the vendor's website, where it is currently in stock.
