SLB-25-120P 25.0 mm Dia. x 120.0 mm FL; Plano-Convex Lens Uncoated

The SLB-25-120P is a Plano-Convex lens with a diameter of 25.0 mm and a focal length of 120.0 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 features a convex shape with a center thickness of 3.3 mm and an edge thickness of 2 mm. The effective focal length (EFL) is 120 mm, and the back focal length (BFL) is 117.8 mm. The inner and outer radii are both 0 mm, indicating a sharp curvature on the convex side.

The lens is uncoated, which means it does not have any anti-reflective or other surface treatments. This can be beneficial in certain applications where specific surface properties are required. However, it's important to note that uncoated lenses can have higher reflectivity, which may affect the performance in high-intensity light applications.

The lens is designed to work with a wavelength of 546.1 nm, making it suitable for a wide range of applications in the visible light spectrum. The lens type is spherical, which is a common choice due to its ease of manufacturing and good optical performance.
