SLB-15-30P 15.0 mm Dia. x 30.0 mm FL; Plano-Convex Lens Uncoated

The SLB-15-30P is a Plano-Convex lens with a diameter of 15.0 mm and a focal length of 30.0 mm. This lens is sourced from OptoSigma, a renowned vendor in the optical industry. The lens is made of n-BK7 Schott, a high-quality optical glass known for its excellent transparency and low auto-fluorescence.

The lens geometry includes a thickness edge of 2.0 mm and a thickness center of 3.9 mm. The effective focal length (EFL) is 30.0 mm, and the radius of curvature (R1) is 15.57 mm. The back focal length (BFL) is 27.4 mm, and both the inner and outer radii are 0 mm, indicating a flat surface on the non-curved side of the lens.

The lens is uncoated, which means it does not have any anti-reflective or other coatings. This may result in higher reflective losses, but it also means the lens can be used in a wider range of wavelengths without the risk of coating damage. The lens is designed for use at a wavelength of 546.1 nm.

The lens type is spherical, which is the most common lens shape due to its ease of manufacturing and high optical quality. The sub-type is Plano-Convex, meaning one side of the lens is flat (plano) and the other side is curved (convex). This design is often used to collimate or focus light, making it suitable for a wide range of optical applications.
