KBX079 25.4 mm Dia. x 250 mm FL; Uncoated; Double-Convex Lens

The KBX079 is a high-quality spherical lens, specifically designed for applications requiring a convex-convex lens shape. Manufactured by MKS/Newport, this lens boasts a diameter of 25.4 mm and a focal length of 250 mm, making it suitable for a wide range of optical systems.

The lens is made from n-BK7 Schott, a popular optical glass due to its excellent optical properties and versatility. It has a refractive index of 1.5168 at 589 nm, making it an ideal choice for many applications. The lens is uncoated, which means it does not have any additional layers to enhance its optical properties. However, this also means it is more cost-effective and suitable for applications where coating is not necessary.

The KBX079 has a center thickness of 3.626 mm and an edge thickness of 3 mm, providing a robust and durable design. The lens's geometry also includes an inner radius of 0 mm and an outer radius of 0 mm, indicating a symmetrical design. The back focal length (BFL) is 248.8 mm, and the effective focal length (EFL) is 250 mm, which are crucial specifications for accurate optical system design.
