G311348000 40 mm Dia. N-BK7 Double-Convex Lens; EFL=300mm Uncoated

The G311348000 is a 40 mm diameter, double-convex lens made from N-BK7 glass, a popular material in the optical industry due to its excellent optical properties. This lens, sourced from Qioptiq Photonics, is uncoated and has an effective focal length (EFL) of 300mm, making it suitable for a wide range of applications.

The lens's geometry is characterized by its base shape, which is circular, and its thickness. The edge thickness is 2mm, while the center thickness is 3.3mm. The radii of curvature for the first and second surfaces are 316.23mm and -316.23mm, respectively. The inner and outer radii are both zero, indicating a symmetrical lens design.

The lens is made from n-BK7 Schott glass, a type of borosilicate crown glass known for its low dispersion and high Abbe number. This makes it an ideal choice for applications that require high image quality and low chromatic aberration.

The wavelength for this lens is 587.6nm, which falls within the visible light spectrum. This means the lens is suitable for use in applications involving visible light, such as photography, microscopy, and beam shaping.

Please note that this lens is uncoated. While uncoated lenses can be more cost-effective, they may be more susceptible to surface reflections and scratching. Coatings can be applied to reduce these issues, but they may also increase the lens's cost and alter its optical properties.
