KBC031AR.14 25.4 mm Dia. x -200 mm FL; AR coated; Double-Concave Lens 430-700nm

The KBC031AR.14 is a high-quality double-concave lens, designed and manufactured by MKS/Newport. This lens, with a base shape of a circle, is specifically engineered for use within the wavelength range of 430-700nm, making it suitable for a wide range of optical applications.

The lens boasts a diameter of 25.4mm, with a thickness at the edge of 3.13mm and a center thickness of 2.5mm. The effective focal length (EFL) is -200mm, and the front and back radii are -207.148mm and 207.148mm respectively. The back focal length (BFL) is -200.82mm, and both the inner and outer radii are 0mm.

The KBC031AR.14 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 New AR-14 fromfigure on both the front and back, enhancing its performance in the specified wavelength range.

This lens is a spherical lens, a common type of lens used in various optical systems due to its simple design and manufacturability. The double-concave design allows for precise control of light paths, making it an ideal choice for applications requiring image reduction or beam convergence.
