SLB-15B-80P 15.0 mm Dia. x 80.4 mm FL; Double-Convex Lens Uncoated
The SLB-15B-80P is a 15.0 mm diameter double-convex lens with a focal length of 80.4 mm, 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 features a base shape of a circle, with a thickness of 2 mm at the edge and 2.7 mm at the center. The effective focal length (EFL) is 80.4 mm, while the back focal length (BFL) is 79.6 mm. The radii of curvature for the first and second surfaces are 83.04 mm and -83.04 mm, respectively.
This lens is uncoated, meaning it does not have any anti-reflective coatings. While this may result in a higher level of internal reflection, it also means the lens is more cost-effective and versatile, as it can be used in a wide range of wavelengths without the risk of coating damage.
The lens is in stock and available for immediate purchase. For more information, including pricing and compatibility with your specific application, please refer to the vendor's website using the provided weblink.
