G311333000 31.5 mm Dia. N-BK7 Double-Convex Lens; EFL=100mm Uncoated

The G311333000 is a 31.5 mm diameter, double-convex lens made from N-BK7 glass, a popular material for its excellent optical properties and high transparency in the visible spectrum. This lens, sourced from Qioptiq Photonics, is uncoated and has an effective focal length (EFL) of 100mm, making it suitable for a wide range of optical applications.

The lens's geometry features a thickness of 2.4mm at the edge and 4.8mm at the center, with a convex-convex shape defined by radii of curvature of 102.92mm for both surfaces. The lens's design is symmetric, which can help minimize optical aberrations. However, it's important to note that the lens is uncoated, which may affect its performance in certain applications, particularly those involving high-intensity light sources or specific wavelength ranges.

The lens's material, N-BK7, is a borosilicate crown glass with a refractive index of approximately 1.517 at the specified wavelength of 587.6nm. This material is known for its low dispersion and high homogeneity, making it a popular choice for many optical systems.
