KBC025 12.7 mm Dia. x -25 mm FL; Uncoated; Double-Concave Lens
The KBC025 is a high-quality double-concave spherical lens, sourced from the reputable vendor MKS/Newport. This lens boasts a 12.7 mm diameter and a focal length of -25 mm, making it ideal for applications that require a strong converging lens. The lens is made from N-BK7 Schott glass, a popular material for its excellent optical properties and versatility.
The lens features a double-concave geometry, with radii of curvature R1 and R2 measured at -26.259 mm and 26.259 mm respectively. This geometry results in a high refractive power, capable of bending light rays to a significant degree. The lens has an edge thickness of 3.76 mm and a center thickness of 2.5 mm, ensuring robustness and durability.
Notably, this lens is uncoated, meaning it does not have any additional layers to enhance its optical properties. While this may limit its performance in certain applications, it also means that the lens is more cost-effective and versatile, suitable for use across a wide range of wavelengths.
The KBC025 is currently in stock and available for immediate purchase. For more information, please refer to the vendor's website linked below.
