KBC073AR.14 50.8 mm Dia. x -250 mm FL; AR coated; Double-Concave Lens 430-700nm
The KBC073AR.14 is a high-quality double-concave lens, designed and manufactured by MKS/Newport. This lens, with a diameter of 50.8 mm, is specifically designed for use in the 430-700nm wavelength range, making it suitable for a wide range of optical applications.
The lens features a base shape of circular geometry, with a thickness at the edge of 4.52 mm and a center thickness of 2.5 mm. The effective focal length (EFL) of this lens is -250 mm, and it has a back focal length (BFL) of -250.82 mm. The first radius of curvature (R1) is -258.824 mm, while the second radius of curvature (R2) is 258.824 mm. The inner and outer radii are both 0 mm.
The KBC073AR.14 lens 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 a new AR-14 coating on both the front and back surfaces, which helps to reduce reflection and increase transmission in the spectral region of use.
This lens is currently in stock and available for immediate purchase. For more information, please refer to the vendor's website at https://www.newport.com/f/ar14-n-bk7-bi-concave-lenses.
