The SLB-25-50P is a 25.0 mm diameter, plano-convex lens with a 50.0 mm focal length, uncoated and sourced from OptoSigma. This lens is made of n-BK7 Schott glass, a popular material for its high refractive index and low dispersion, making it ideal for a wide range of optical applications.
The lens geometry features a 2.0 mm edge thickness and a 5.2 mm center thickness, with a clear aperture of 25.0 mm. The radius of curvature for the convex surface is 25.95 mm, resulting in a back focal length of 46.6 mm. The lens has no coating, which means it does not have any anti-reflective or other surface treatments. This can be beneficial in certain applications where a natural lens surface is preferred.
The lens is designed to operate at a wavelength of 546.1 nm, making it suitable for use in monochromatic light applications. Its spherical shape allows for efficient light bending and focusing, making it a versatile choice for various optical systems.
Please note that the lens is uncoated, which may result in unwanted reflections. However, this can be mitigated by adding an anti-reflective coating, which is not included in this product but can be requested separately.
