45-237 20.0mm Dia. x 20.0mm FL; Uncoated; Plano-Convex Lens

The 45-237 is a 20.0mm diameter, 20.0mm focal length Plano-Convex lens, sourced from the renowned optical components manufacturer, Edmund Optics. This uncoated lens is designed for use in a wide range of optical applications, thanks to its high-quality Schott N-SF11 glass material.

The lens's geometry is characterized by a 1mm edge thickness and a 4.6mm center thickness, with an effective focal length (EFL) of 20mm. The radius of curvature (R1) is 15.7mm, and the back focal length (BFL) is 17.42mm. The lens's design is spherical, ensuring excellent image quality and minimal optical aberrations.

The lens's base shape is circular, making it suitable for use in various optical systems. The lack of coating on this lens ensures high light transmission, but it may be more susceptible to environmental factors such as dust and moisture. Therefore, it's recommended for use in controlled environments.

This lens is an excellent choice for applications that require a high-quality, uncoated Plano-Convex lens. Its specifications make it ideal for use in imaging systems, beam shaping, and other applications where a high-quality, spherical lens is required.
