SLB-25.4-90P 25.4 mm Dia. x 90.0 mm FL; Plano-Convex Lens Uncoated

The SLB-25.4-90P is a Plano-Convex lens with a diameter of 25.4 mm and a focal length of 90.0 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 edge thickness of 1.9 mm and center thickness of 3.7 mm. The effective focal length (EFL) is 90 mm, and the radius of curvature (R1) is 46.71 mm. The back focal length (BFL) is 87.6 mm, and both the inner and outer radii are 0 mm.

This lens is uncoated, meaning it does not have any anti-reflective or other coatings applied to its surfaces. This can be advantageous in certain applications where the natural properties of the material are desired, or where cost considerations are a factor. However, it's important to note that uncoated lenses can suffer from increased reflection and reduced transmission, especially at higher wavelengths or in high-precision applications.

The lens is designed to operate at a wavelength of 546.1 nm, making it suitable for a wide range of applications in the visible light spectrum. Its spherical shape ensures consistent optical performance and ease of integration into optical systems.
