48-759 20.0mm Dia. x 40.0mm FL; NIR I Coated; Plano-Convex Lens NIR I 600-1050nm
This is a 20.0mm diameter by 40.0mm focal length Plano-Convex lens, offered by Edmund Optics. The lens is coated with EDM NIR-I standard curve on both the front and back surfaces, ensuring optimal performance within the near-infrared spectrum of 600-1050nm.
The lens is made of n-BK7 Schott, a popular optical glass due to its excellent optical properties and versatility. The geometry of the lens includes a 2.32mm edge thickness and a 4.9mm center thickness, providing robustness and durability. The lens's effective focal length (EFL) is 40mm, and its radius of curvature (R1) is 20.67mm, contributing to its plano-convex shape.
The lens's back focal length (BFL) is 36.77mm, and it has no inner or outer radius, indicating a uniform curvature. The lens's shape is spherical, a common choice for its simplicity and wide range of applications.
The lens's web links are valid and indicate that it is currently in stock, making it readily available for immediate use. This lens is an excellent choice for applications that require a high-quality, near-infrared, plano-convex lens.
