45-358 9.0mm Dia. x 45.0mm FL; Plano-Convex Lens Uncoated

The 45-358 is a 9.0mm diameter, 45.0mm focal length Plano-Convex lens offered by Edmund Optics. This uncoated lens is designed for use in a wide range of optical systems, offering versatility and reliability.

The lens is fabricated from N-BK7 Schott glass, a popular choice due to its excellent optical properties and high Abbe number. The Plano-Convex design features a flat plane on one side and a curved plane on the other, with a radius of curvature of 23.26mm. This design is often used to collimate or focus light in various applications.

The lens has a center thickness of 1.54mm and an edge thickness of 1.1mm, providing a robust structure while maintaining a low profile. The effective focal length (EFL) is 45mm, and the back focal length (BFL) is 43.98mm, offering a long focal length for increased magnification or narrower field of view.

The 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 susceptible to damage and contamination, making it suitable for harsh environments.

This lens is ideal for applications that require a long focal length, such as microscopy, beam shaping, or laser systems. It is currently in stock, as indicated by its weblink status, making it readily available for immediate use.
