SLB-20-30P 20.0 mm Dia. x 30.0 mm FL; Plano-Convex Lens Uncoated
The SLB-20-30P is a Plano-Convex lens with a diameter of 20.0 mm and a focal length of 30.0 mm, sourced from the reputable vendor OptoSigma. This lens is made of the high-quality material n-BK7 schott, which is known for its excellent optical properties.
The lens geometry includes a thickness edge of 2.0 mm and a thickness center of 5.6 mm, providing a robust structure. 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 26.3 mm, and the inner and outer radii are both 0 mm, indicating a flat surface on the opposite side of the convex curve.
The lens is uncoated, which means it does not have any additional layers to enhance its optical properties. This may be suitable for applications where specific coatings are not required or desired. The wavelength for this lens is 546.1 nm.
