111-1534E 50.8 mm Dia. x 500 mm FL; Uncoated; Double-Convex Lens
The 111-1534E is a double-convex lens, characterized by its spherical shape and circular base. This lens, sourced from EKSMA Optics, boasts a diameter of 50.8 mm and a center thickness of 6 mm, with an edge thickness of 4.6 mm. The lens's effective focal length (EFL) is 500 mm, making it suitable for applications requiring long focal lengths.
The lens's geometry is defined by its radii of curvature, with r1 at 475.1 mm and r2 at -475.1 mm. The inner and outer radii are both zero, indicating a symmetrical lens design. The lens is made from UVFS MAL-1965 material, optimized for use at a wavelength of 355 nm.
Notably, this lens is uncoated, which may affect its performance in certain applications. Coatings are often applied to lenses to enhance their durability, reduce surface reflections, or alter their optical properties. However, an uncoated lens can be advantageous in specific scenarios, such as when minimal reflection is desired or when cost is a primary concern.
