KBC025AR.14 12.7 mm Dia. x -25 mm FL; AR coated; Double-Concave Lens 430-700nm

The KBC025AR.14 is a high-quality double-concave lens, designed with a base shape of a circle and a spherical geometry. This lens, sourced from the reputable vendor MKS/Newport, boasts a diameter of 12.7 mm and a center thickness of 2.5 mm, ensuring a compact and efficient design. The edge thickness is 3.76 mm, providing robustness and durability.

The lens is made from the renowned material N-BK7 Schott, a borosilicate crown glass known for its excellent optical properties, including low dispersion and high transmission in the visible spectrum. The effective focal length (EFL) of this lens is -25 mm, making it suitable for a variety of applications that require concave lenses.

The KBC025AR.14 features an anti-reflective (AR) coating on both the front and back surfaces, specifically the new AR-14 fromfigure coating. This coating enhances the lens's performance by reducing surface reflections and increasing transmission, particularly in the 430-700 nm wavelength range. This makes the lens ideal for use in systems where high transmission and minimal reflection are critical.

The lens's inner and outer radii are 0 mm, indicating a symmetrical design, which can be beneficial in many optical applications. The lens is available directly from MKS/Newport, and the provided weblink indicates that it is currently in stock, ensuring quick and easy acquisition for your optical system needs.
