33-412 40mm Dia. x 200mm FL Uncoated; Double-Convex Lens
The 33-412 is a 40mm diameter, double-convex lens with a focal length of 200mm, sourced from Edmund Optics. This lens is uncoated, which means it does not have any additional layers to enhance light transmission or protect the surface. The lens's base shape is circular, and it is a spherical lens, specifically a convex-convex lens.
The lens's geometry includes a thickness of 6.05mm at the edge and 8mm at the center. The effective focal length (EFL) is 200mm, and the radii of curvature are 205.35mm for the first surface and -205.35mm for the second surface. The back focal length (BFL) is 197.35mm. The lens is made of N-BK7 Schott, a popular optical glass known for its excellent optical properties.
The lens is designed to operate at a wavelength of 587.6nm. This wavelength falls within the visible light spectrum, making this lens suitable for applications that involve visible light. However, it's important to note that the lens's performance may vary depending on the specific application and the conditions under which it is used.
