KPC043AR.18 25.4 mm Dia. x -25 mm FL; IR coated; Plano-Concave Lens 1000-1550nm
The KPC043AR.18 is a Plano-Concave Lens, a type of spherical lens, sourced from MKS/Newport. It boasts a diameter of 25.4 mm and a center thickness of 2.5 mm, with an edge thickness of 9.4 mm. The lens is designed for use within the wavelength range of 1000-1550nm, with a focal length of -25 mm.
The lens is made from N-BK7 Schott, a popular optical glass due to its excellent optical properties and relatively low cost. The lens's geometry is defined by an inner radius of 0 mm and an outer radius of 0 mm, with a surface curvature of -12.92 mm on the first surface and a back focal length of -26.64 mm.
The KPC043AR.18 features a New AR-18 coating on both the front and back surfaces, enhancing its performance in the infrared spectrum. This coating reduces reflection and increases transmission, making it ideal for applications that require high-quality, low-loss optical transmission.
