32-904 25mm Dia. x 400mm FL UnCoated; DCX N-K5 Lens
The 32-904 is a 25mm diameter spherical lens with a focal length of 400mm, sourced from Edmund Optics. This uncoated lens boasts a convex-convex base shape and a circular geometry, making it suitable for a wide range of optical applications.
The lens has a center thickness of 5mm and an edge thickness of 4.63mm, contributing to its robust construction. The base shape is spherical, with radii of curvature R1 and R2 measured at 417.54mm and -417.54mm respectively. The back focal length (BFL) of the lens is 398.75mm.
The lens is crafted from N-K5 Schott glass, a material known for its excellent optical properties. The material is designed to operate at a wavelength of 587.6nm, ensuring high-quality performance in its intended application.
Notably, the lens is uncoated, meaning it does not have any anti-reflective or other surface coatings. This may result in increased reflection at the air-glass interface, but it also means the lens is more cost-effective and easier to clean.
According to the vendor's website, the lens is currently in stock, making it readily available for immediate use. For more information, users are encouraged to visit the provided weblink.
