111-0148E 12.7 mm Dia. x 400 mm FL; Uncoated; Double-Convex Lens

The 111-0148E is a high-quality double-convex lens, sourced from EKSMA Optics, a renowned vendor known for their extensive catalog of optical components. This lens boasts a 12.7 mm diameter and a focal length of 400 mm, making it suitable for a wide range of optical applications.

The lens is crafted from BK7 Schott, a popular optical glass due to its excellent optical properties and versatility. It has a refractive index of 1.5168 at 546 nm, ensuring high-quality light transmission. The lens's geometry features a thickness of 1.9 mm at the edge and 2 mm at the center, providing a robust structure while maintaining a sleek profile.

The 111-0148E is an uncoated lens, offering a cost-effective solution for applications where high transmission and low reflection are not critical. However, it's important to note that uncoated lenses can be susceptible to surface reflections, which may affect the overall performance in high-precision applications.

This lens is a spherical design, specifically a biconvex lens, meaning it has two convex surfaces. This design provides a wide field of view and low spherical aberration, making it ideal for imaging applications. The lens's geometry also includes an inner radius of 0 mm and an outer radius of 0 mm, indicating a symmetrical design.
