G311308000 22.4 mm Dia. N-BK7 Double-Convex Lens; EFL=25mm Uncoated

This is a G311308000 22.4 mm Dia. N-BK7 Double-Convex Lens, featuring an effective focal length (EFL) of 25mm and sourced from the renowned optical components vendor, Qioptiq Photonics. The lens is uncoated, offering a high-quality, cost-effective solution for various applications.

The lens boasts a base shape of a circle with a diameter of 22.4mm and a thickness of 1.6mm at the edge, transitioning to 7mm at the center. The double-convex design, characterized by both surfaces curving outward, provides excellent focusing capabilities. The radii of curvature for the first and second surfaces are 24.406mm and -24.406mm, respectively.

The lens material is N-BK7, a high-grade borosilicate glass known for its excellent optical properties, including low auto-fluorescence, high transmittance, and superior homogeneity. This material is widely used in various applications, such as beam shaping, collimation, and imaging.

The G311308000 lens operates at a wavelength of 587.6nm, making it suitable for applications in the visible light spectrum. Its spherical shape ensures consistent optical performance across the entire surface, while the uncoated design offers a more affordable option without compromising quality.
