G311324331 25.4 mm Dia. N-BK7 Double-Convex Lens; EFL=100mm

The G311324331 is a high-quality double-convex lens offered by Qioptiq Photonics, a renowned vendor in the field of precision optics. This lens, with a diameter of 25.4 mm, is designed for use in a wide range of optical applications, thanks to its robust construction and precise specifications.

The lens is made from N-BK7, a popular glass type known for its excellent optical properties. This material is characterized by a high refractive index and low dispersion, making it an ideal choice for applications that require high image quality and minimal chromatic aberration. The lens's geometry, which includes a thickness of 5.4 mm at the edge and 7 mm at the center, is optimized for a focal length of 100 mm (EFL).

The G311324331 features a symmetric convex-convex design, with radii of curvature of 102.92 mm for both the front and back surfaces. This shape allows for a wide range of applications, including focusing and imaging. The lens's inner and outer radii are zero, indicating a uniform curvature across the lens surface.

In terms of coatings, this lens is equipped with a Qio AR/RALVIS AOI 45 coating on both the front and back surfaces. This anti-reflection coating reduces surface reflections, thereby improving transmission and enhancing the overall performance of the lens.

Please note that the lens is designed for use at a specific wavelength of 587.6 nm. This wavelength falls within the visible light spectrum, making the lens suitable for applications involving visible light.
