G063155329 31.5 mm Dia. N-BK7 Mounted Double-Convex Lens; EFL=130mm 1064nm
This is a mounted double-convex lens, type G063155329, with a diameter of 31.5 mm, sourced from Qioptiq Photonics. The lens is made of N-BK7, a popular glass type in the optical industry, known for its excellent optical properties and versatility.
The lens features a double-convex geometry, meaning it has two spherical surfaces that curve outwards, away from the center of the lens. This design is often used to collimate or focus light, making it suitable for a wide range of applications.
The lens has an effective focal length (EFL) of 130 mm at a wavelength of 1064 nm. The EFL is a measure of the lens's focusing power and is an important parameter when selecting a lens for a specific application.
The lens's thickness at the edge is 2.2 mm, while its center thickness is 4 mm. The inner and outer radii are 0, indicating that the lens has no peripheral or central curvature beyond its spherical surfaces.
The lens is coated with Qio HP Nbar ARHS-YAG on both the front and back surfaces. This coating is designed to reduce reflection and enhance transmission, making the lens more efficient in transmitting light.
