The 87-911 is a Plano-Convex lens with a diameter of 5.0mm and a focal length of 25.0mm. This lens is sourced from Edmund Optics, a renowned vendor in the optical industry. The lens is uncoated, which means it does not have any additional layers to enhance its optical properties or protect it from environmental factors.
The lens's geometry includes a thickness edge of 1.36mm and a thickness center of 1.6mm. The effective focal length (EFL) is 25.0mm, and the radius of curvature (R1) is 12.92mm. The back focal length (BFL) is 23.95mm, and both the inner and outer radii are 0mm, indicating a flat surface on the opposite side of the convex surface.
The lens is made of N-BK7 Schott, a popular optical glass due to its excellent optical properties and versatility. The wavelength for this lens is 587.6nm. This lens is spherical in shape, meaning it has a curved surface that is a portion of a sphere.
Please note that the lens's coating is listed as empty, indicating that it does not have any special coatings. This could affect the lens's performance in certain applications, so it's essential to consider this factor when selecting optical components.
