SLB-50-400P 50.0 mm Dia. x 400.0 mm FL; Plano-Convex Lens Uncoated

The SLB-50-400P is a Plano-Convex lens with a diameter of 50.0 mm and a focal length of 400.0 mm. This lens is sourced from OptoSigma, a renowned vendor in the optical industry. The lens is made of n-bk7 schott material, a popular choice for its high refractive index and low dispersion.

The lens geometry is characterized by its spherical shape, with a thickness of 3.0 mm at the edge and 4.5 mm at the center. The effective focal length (EFL) is 400.0 mm, and the radius of curvature (R1) is 207.6 mm. The back focal length (BFL) is 397.0 mm, and both the inner and outer radii are 0 mm, indicating a flat surface on the opposite side of the convex surface.

The lens is uncoated, meaning it does not have any anti-reflective or other coatings applied to its surfaces. This can be beneficial in certain applications where specific coatings may interfere with the desired optical properties. However, it is essential to consider that uncoated lenses may have higher reflectivity, which could lead to reduced transmission and increased scattering of light.

The wavelength for this lens is 546.1 nm, which is within the visible light spectrum. This makes the SLB-50-400P suitable for various applications, such as imaging, beam shaping, and laser systems, among others.

According to the vendor's website, the SLB-50-400P is currently in stock, ensuring quick delivery and availability for your optical project needs.
