The SPC019 is a Plano-Concave Spherical Lens, sourced from the reputable vendor MKS/Newport. This lens boasts a diameter of 25.4 mm and a center thickness of 2.5 mm, with an edge thickness of 3.07 mm, providing a robust and durable structure. The lens is designed for use with a wavelength of 589 nm.

The lens's base shape is circular, and it features an effective focal length (EFL) of -250 mm, making it suitable for applications that require a concave lens. The lens's inner radius is 0 mm, and the outer radius is also 0 mm, indicating a uniform curvature throughout. The back focal length (BFL) is -251.71 mm, which is a crucial factor to consider when integrating this lens into an optical system.

The lens is made from UVFS material, specifically UVFS Mal-1965, which is known for its optical quality and durability.
