LM01-25-1K 25.4 mm Dia. N-BK7 Positive Meniscus Lens; EFL=1000mm Uncoated
The LM01-25-1K is a spherical lens with a base shape of a circle, sourced from CeNing Optics. This lens is a positive meniscus type, characterized by a convex-concave geometry. The lens has a diameter of 25.4 mm and a thickness at the edge of 3.3 mm, while the center thickness is slightly more at 3.5 mm.
The effective focal length (EFL) of this lens is 1000mm, making it suitable for applications that require long-focus capabilities. The first radius of curvature (R1) is 278.34 mm, and the second radius (R2) is 600 mm. The back focal length (BFL) is 993.7 mm. The lens does not have any coating specified, which means it is delivered in its raw, uncoated state.
The lens is made of N-BK7 Schott, a popular material in the optical industry due to its excellent optical properties. The lens is designed to work with a wavelength of 546.1 nm. The inner and outer radii are both zero, indicating a uniform curvature throughout the lens.
