111-1517E 50.8 mm Dia. x 150 mm FL; Uncoated; Double-Convex Lens

This is a 111-1517E Double-Convex Lens, a high-quality optical component sourced from EKSMA Optics. The lens boasts a diameter of 50.8 mm and a focal length of 150 mm, making it suitable for a wide range of optical applications.

The lens is spherical in shape, with a base shape of a circle. It features a double-convex design, characterized by two convex surfaces. The first surface has a radius of curvature of 141.6 mm, while the second surface has a radius of curvature of -141.6 mm. This design allows for efficient light transmission and focusing.

The lens has a center thickness of 7.5 mm and an edge thickness of 2.9 mm. The inner radius is 0 mm, and the outer radius is also 0 mm. These dimensions contribute to the lens's overall optical performance and durability.

The lens is made from UVFS MAL-1965, a material specifically designed for use in the ultraviolet spectrum. The wavelength of this lens is 355 nm, further emphasizing its suitability for UV applications.

Notably, this lens is uncoated. Coatings are often applied to lenses to enhance their optical performance by reducing reflections, increasing transmission, or providing other benefits. However, this lens is designed to function optimally without a coating, making it a cost-effective choice for many applications.
