17-337 50mm Dia. UVFS Aspheric Lens; EFL=100mm; NA=0.23 Uncoated

The 17-337 is a high-quality aspheric lens, sourced from the renowned optical vendor, Edmund Optics. This lens is characterized by its 50mm diameter and a numerical aperture (NA) of 0.23, making it suitable for a wide range of applications. The lens is made from UV fused silica, a material known for its excellent transparency across a broad spectrum, including the ultraviolet (UV) range, hence the "UVFS" in the catalog number.

The lens's geometry is meticulously designed, with an inner radius of 0 and an outer radius of 0, indicating a symmetrical structure. The effective focal length (EFL) is 100mm, suggesting a moderate to high magnification capability. The lens's thickness at the edge is 5.73mm, while the center thickness is 14mm, providing structural rigidity and minimizing optical distortions.

The aspheric design of the lens, represented by the 'Aspheric' subtype, allows for superior optical performance compared to traditional spherical lenses. The 'r1' and 'r2' parameters, which are -0.717 and 0 respectively, are key curvature parameters that contribute to the lens's unique optical properties.

Notably, this lens is uncoated, meaning it does not have any anti-reflective or other surface coatings. While this may result in higher reflective losses, it can also provide certain benefits, such as increased durability and resistance to environmental factors.
