G311329331 8 mm Dia. N-BAK4 Double-Convex Lens; EFL=7mm
The G311329331 is a high-quality spherical lens from Qioptiq Photonics, featuring a base shape of a circle and a double-convex design. This lens has a diameter of 8 mm and a center thickness of 3.4 mm, with an edge thickness of 1.1 mm. The effective focal length (EFL) of this lens is 7 mm, making it suitable for various optical applications.
The lens is made from N-BAK4, a type of optical glass known for its excellent optical properties, including high transmittance and low dispersion. This material is identified by the Material ID "n-bak4 schott" in the item data.
The G311329331 lens is coated with Qio AL RALVIS AOI 45 on both the front and back surfaces. This anti-reflection coating reduces surface reflections, thereby increasing the amount of light transmitted through the lens. The wavelength for this coating is 587.6 nm.
Please note that the inner and outer radii of this lens are both 0, indicating that this lens does not have any curvature on its edges. This further emphasizes the double-convex nature of the lens.
