SLB-40-500P 40.0 mm Dia. x 500.0 mm FL; Plano-Convex Lens Uncoated
The SLB-40-500P is a Plano-Convex lens with a diameter of 40.0 mm and a focal length of 500.0 mm, sourced from the reputable vendor OptoSigma. This lens is made of the high-quality material n-BK7 Schott, ensuring durability and reliability.
The lens geometry includes an edge thickness of 2.0 mm and a center thickness of 2.8 mm, with a back focal length of 498.2 mm. The inner and outer radii are both 0 mm, indicating a plano surface on one side and a curved surface on the other. The radius of curvature of the curved surface is 259.5 mm.
The lens is uncoated, which means it does not have any anti-reflective or other coatings. This may result in a higher level of reflection, but it also means that the lens is less susceptible to damage from environmental factors.
The lens is designed to work with a wavelength of 546.1 nm, making it suitable for a wide range of optical applications. The shape of the lens is spherical, which is a common choice for many optical systems due to its simplicity and versatility.
