33-394 25mm Dia. x 200mm FL Uncoated; Double-Convex Lens
The 33-394 is a 25mm diameter, double-convex lens with a focal length of 200mm, sourced from the renowned optical components vendor, Edmund Optics. This lens, designed for general-purpose use, is uncoated, offering users a cost-effective solution for their optical needs.
The lens's base shape is circular, with a thickness of 4.24mm at the edge and 5mm at the center. It boasts an effective focal length (EFL) of 200mm, making it suitable for a wide range of applications. The first radius of curvature (R1) is 205.865, while the second radius (R2) is -205.865, indicating its double-convex nature. The back focal length (BFL) is 198.35mm, and the lens has no inner or outer radius, indicating a uniform curvature throughout.
The lens is made of n-BK7 Schott, a high-quality optical glass known for its excellent transparency and low dispersion. It is designed to operate at a wavelength of 587.6nm. The lens's shape is spherical, a common choice for its ease of manufacturing and versatility. As an uncoated lens, it does not have any anti-reflective coatings, which can be a consideration depending on the specific application.
