LM01-25-175 25.4 mm Dia. N-BK7 Positive Meniscus Lens; EFL=175mm Uncoated

The LM01-25-175 is a 25.4 mm diameter spherical lens with a positive meniscus shape, sourced from CeNing Optics. This lens is designed for use in systems operating at a wavelength of 546.1 nm. The lens features a convex-concave geometry, with a center thickness of 4 mm and an edge thickness of 3.1 mm, providing a balance between optical performance and mechanical robustness.

The lens's base shape is circular, ensuring uniform performance in all directions. The effective focal length (EFL) of this lens is 175 mm, making it suitable for applications that require moderate magnification or collimation. The back focal length (BFL) is 171.2 mm, which should be considered when designing the optical layout of the system.

The lens is made of N-BK7 glass, a common and versatile material in optical systems due to its excellent optical properties and availability. However, it's important to note that this lens is uncoated. While uncoated lenses can be cost-effective, they may be more susceptible to surface reflections and could benefit from an anti-reflective coating, depending on the application.
