33-396 25mm Dia. x 200mm FL; VIS 0deg Coated; Double-Convex Lens VIS 0deg 425-675nm
The 33-396 is a Double-Convex Lens, a type of Spherical Lens, sourced from Edmund Optics. This lens boasts a diameter of 25mm and a focal length of 200mm, making it suitable for a wide range of optical applications. The lens is made from n-BK7 Schott, a high-quality optical glass known for its excellent transparency and low auto-fluorescence.
The lens features a standard curve coating on both the front and back surfaces, specifically the edm vis-0 std curve. This coating is designed to enhance the lens's performance in the visible light spectrum, particularly between 425 and 675nm. The coating reduces surface reflections, improving light transmission and enhancing the overall image quality.
The geometry of the lens is also noteworthy. The lens has an inner radius of 0mm and an outer radius of 0mm, indicating a uniform thickness. The edge thickness is 4.24mm, while the center thickness is 5mm. The back focal length (BFL) is 198.35mm, and the effective focal length (EFL) is 200mm.
