LM01-25-125 25.4 mm Dia. N-BK7 Positive Meniscus Lens; EFL=125mm Uncoated
The LM01-25-125 is a spherical lens with a base shape of a circle, sourced from CeNing Optics. This lens is a positive meniscus type, meaning it has a convex-concave geometry. The lens has a diameter of 25.4 mm and a thickness at the edge of 2.8 mm, while the center thickness is 4 mm. The effective focal length (EFL) of this lens is 125 mm, making it suitable for applications that require a longer focal length.
The lens is made of N-BK7, a type of glass commonly used in optical applications due to its excellent optical properties. The radii of curvature for this lens are R1 = 38.47 mm and R2 = 90 mm. The back focal length (BFL) of this lens is 121.8 mm. The lens does not have any coating, as indicated in the item data.
The lens is designed to work with a wavelength of 546.1 nm. The item data does not provide information about any additional coatings or treatments that the lens may have, so it can be assumed that it is uncoated. This lens is currently in stock and available for purchase, as indicated by the "weblink status" in the item data.
