G311328000 6 mm Dia. N-BAK4 Double-Convex Lens; EFL=5mm Uncoated
The G311328000 is a 6 mm diameter, double-convex lens made from N-BAK4 material, sourced from Qioptiq Photonics. This lens is uncoated and features a high refractive index, making it suitable for a wide range of optical applications.
The lens has an effective focal length (EFL) of 5mm, which is the distance from the lens's center to the focal point when the lens is imaging an object at infinity. This EFL value indicates a relatively compact and powerful lens, ideal for use in systems with limited space.
The lens's geometry includes a thickness of 0.9mm at the edge and 2.9mm at the center. The radii of curvature for the first and second surfaces are 5.085mm and -5.085mm, respectively. The lens's inner and outer radii are both 0, indicating a symmetrical design.
The lens is made from n-BAK4 Schott material, a type of optical glass known for its excellent optical properties. This material has a high Abbe number, which reduces chromatic aberration, and a high refractive index, which increases the lens's focusing power.
The lens is uncoated, meaning it does not have any anti-reflective coatings. While this may result in higher reflective losses, it also means the lens is less susceptible to damage from environmental factors.
