The 37-798 12.5mm Dia. x 75.0mm FL; Plano-Convex Lens Uncoated is a high-quality optical component sourced from Edmund Optics. This lens, with its spherical geometry, is designed for use in a wide range of optical applications.
The lens features a plano-convex shape, which means one side is flat (plano) and the other side is curved (convex). This design is beneficial in applications where a collimated beam needs to be focused to a point or a divergent beam needs to be collimated. The lens has a diameter of 12.5mm and a center thickness of 1.7mm, making it suitable for use in compact optical systems.
The lens is made from N-BK7 Schott glass, a common and versatile optical material. This material is known for its excellent optical properties, including a high Abbe number and low dispersion, making it ideal for use in achromatic doublets and other high-performance optical systems.
The lens has an effective focal length (EFL) of 75mm, which is the distance from the lens to the point where it focuses a collimated beam. This EFL makes the lens suitable for use in moderate to long focal length applications.
The lens is uncoated, meaning it does not have any anti-reflective coatings. While this can lead to higher reflective losses at the air-glass interfaces, it can also be beneficial in applications where broadband anti-reflection coatings are not desired.
