G311383322 12.7 mm Dia. N-BK7 Double-Convex Lens; EFL=30mm 450-700nm
This is a G311383322 model lens from Qioptiq Photonics, a renowned vendor in the field of precision optics. The lens is a symmetric convex-convex type, featuring a base shape of a circle. It has a diameter of 12.7 mm and a thickness of 1.6 mm at the edge, with a center thickness of 3 mm. The effective focal length (EFL) of this lens is 30 mm, making it suitable for a range of applications.
The lens is made of n-BK7 Schott, a high-quality optical glass known for its excellent transmission properties and low auto-fluorescence. The curvature of the lens is defined by two radii: the first radius (r1) is 30.287 mm, and the second radius (r2) is -30.287 mm, indicating a double-convex lens. The inner and outer radii are both 0, suggesting a uniform curvature.
The lens is designed for use in the wavelength range of 450-700 nm, centered around the visible light spectrum. It comes with a front and back coating of qio bbar arb2visnbk7, which enhances its durability and performance in its intended wavelength range. The lens's shape is spherical, a common choice for its ease of manufacturing and versatility in optical systems.
