SLB-30-35P 30.0 mm Dia. x 35.0 mm FL; Plano-Convex Lens Uncoated
The SLB-30-35P is a Plano-Convex lens with a diameter of 30.0 mm and a focal length of 35.0 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 9.9 mm. The effective focal length (EFL) is 35.0 mm, and the radius of curvature (R1) is 18.17 mm. The back focal length (BFL) is 28.5 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 and a lower transmission rate compared to coated lenses. However, uncoated lenses are often more cost-effective and can be suitable for applications where such losses are acceptable or can be mitigated.
The lens is designed to work with a wavelength of 546.1 nm, making it suitable for a wide range of optical applications. Its spherical shape ensures a uniform curvature, providing a high degree of focusing accuracy.
