KBX022AR.18 12.7 mm Dia. x 12.7 mm FL; IR coated; Double-Convex Lens IR 1000-1550nm
This is a high-quality double-convex lens, designed and manufactured by MKS/Newport, a renowned vendor in the optical industry. The lens, identified as KBX022AR.18, is a spherical lens with a base shape of a circle, featuring a diameter of 12.7 mm and a thickness at the edge of 3 mm. The center thickness of the lens is 6.68 mm, and it has an effective focal length (EFL) of 12.7 mm.
The lens is made from N-BK7 Schott, a popular optical glass due to its excellent optical properties and wide transparency range. The curvature of the lens is defined by two radii, R1 and R2, which are 11.868 mm and -11.868 mm respectively, indicating a converging lens. The back focal length (BFL) of the lens is 10.26 mm.
The lens is coated with New AR-18, a broadband anti-reflective coating designed for the infrared region, specifically for wavelengths between 1000 and 1550 nm. This coating ensures minimal reflection and maximum transmission, making it ideal for applications that require high-transmission optics in the infrared spectrum.
