SLB-07B-08P 7.0 mm Dia. x 8.6 mm FL; Double-Convex Lens Uncoated
The SLB-07B-08P is a 7.0 mm diameter double-convex lens with a focal length of 8.6 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 3.6 mm at the center. The effective focal length (EFL) is 8.6 mm, while the back focal length (BFL) is 7.4 mm. The radii of curvature for the first and second surfaces are 8.3 mm and -8.3 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 variety of wavelengths without the need for specialized coatings.
The SLB-07B-08P is currently in stock and available for purchase through the OptoSigma website. With its high-quality materials and precise specifications, this lens is a reliable choice for any optical system that requires a double-convex lens.
