SLB-40-450P 40.0 mm Dia. x 450.0 mm FL; Plano-Convex Lens Uncoated

The SLB-40-450P is a Plano-Convex lens with a diameter of 40.0 mm and a focal length of 450.0 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 is characterized by its base shape, which is circular, and its geometry specifications. The thickness at the edge of the lens is 2.0 mm, while the thickness at the center is 2.9 mm. The effective focal length (EFL) is 450.0 mm, and the radius of curvature (R1) is 233.55 mm. The back focal length (BFL) is 448.1 mm, and both the inner and outer radii are 0 mm.

The lens is uncoated, meaning it does not have any anti-reflective or other coatings. This may result in a higher level of reflection at the lens surfaces, which could affect the overall transmission and image quality. However, uncoated lenses are often more cost-effective and can be suitable for many applications.

The lens is designed to work with a wavelength of 546.1 nm, making it suitable for use in a wide range of optical systems. Its spherical shape ensures excellent image quality and low distortion, making it a reliable choice for various applications.
