The SLB-05B-15P is a 5.0 mm diameter double-convex lens, offering a focal length of 15.3 mm, sourced from OptoSigma. This lens is made of the high-quality material n-BK7 Schott, a borosilicate crown glass known for its excellent optical properties.
The lens features a base shape of a circle, with a thickness of 1.2 mm at the edge and 1.6 mm at the center. The effective focal length (EFL) is 15.3 mm, while the back focal length (BFL) measures 14.7 mm. The radii of curvature for the first and second surfaces are 15.57 mm and -15.57 mm, respectively.
This lens is uncoated, meaning it does not have any anti-reflective coatings. While this may result in a higher reflectance of incident light, it also means the lens is more cost-effective and versatile, making it suitable for a wide range of applications.
The lens is designed to operate at a wavelength of 546.1 nm, and its geometry is spherical. The lens is available for purchase through the OptoSigma website, where you can find more detailed specifications and pricing information.
