SLB-15B-70P 15.0 mm Dia. x 70.5 mm FL; Double-Convex Lens Uncoated
The SLB-15B-70P is a 15.0 mm diameter double-convex lens with a focal length of 70.5 mm, sourced from OptoSigma. This lens is made of n-bk7 schott material, a popular choice 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 2.8 mm at the center. The effective focal length (EFL) is 70.5 mm, while the back focal length (BFL) is 69.5 mm. The radii of curvature for the first and second surfaces are 72.66 mm and -72.66 mm, respectively.
Notably, this lens is uncoated, which means 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 currently in stock and available for purchase through the provided weblink. With its high-quality materials and precise specifications, the SLB-15B-70P is a reliable choice for various optical systems and setups.
