The LA5215 is a Plano-Convex lens with a diameter of 50.8 mm, sourced from the reputable optical components manufacturer, Thorlabs. This lens is made of Calcium Fluoride (CaF2) with a Mohs hardness of 3, making it an ideal choice for applications that require a material with excellent transparency in the ultraviolet, visible, and near-infrared regions.
The lens features an effective focal length (EFL) of 150 mm, which is the distance from the lens's center to the focal point when the lens is placed in an optical system. This EFL makes the LA5215 suitable for various applications, including imaging systems, beam shaping, and laser applications.
The LA5215 has a clear aperture of 50.8 mm, providing a wide field of view and high light gathering capability. The lens's geometry includes a thickness of 3 mm at the edge and 8.2 mm at the center, offering robustness and stability in optical systems.
Notably, this lens is uncoated, meaning it does not have any anti-reflective coatings. While this may result in higher reflective losses, it also means the lens is less prone to damage and contamination, making it suitable for harsh environments.
