111-0526E 50.8 mm Dia. x 500 mm FL; Uncoated; Double-Convex Lens

The 111-0526E is a high-quality Double-Convex Lens, sourced from EKSMA Optics, a renowned vendor known for their extensive catalog of optical elements. This lens, with its spherical shape, is designed for use in a wide range of optical applications.

The lens boasts a diameter of 50.8 mm and a focal length of 500 mm, making it a versatile choice for various optical setups. The double-convex design, characterized by its two convex surfaces (r1: 517.9, r2: -517.9), provides a strong focusing power, ideal for applications requiring high magnification or light concentration.

The lens is crafted from n-BK7 Schott, a popular optical glass known for its excellent optical properties and high homogeneity. This material ensures high transmittance across a wide spectrum, making the lens suitable for use with a wavelength of 546 nm.

The lens has a center thickness of 5 mm and an edge thickness of 3.8 mm, providing robustness and durability. The inner and outer radii are 0, indicating a uniform curvature across the lens surface.

Notably, this lens is uncoated, offering users the flexibility to apply their preferred coating based on their specific application requirements. However, it's essential to consider that uncoated lenses may have higher surface reflections, which could impact the overall system performance.
