G311331000 31.5 mm Dia. N-SK2 Double-Convex Lens; EFL=30mm Uncoated

The G311331000 is a 31.5 mm diameter double-convex lens, manufactured by Qioptiq Photonics, a renowned provider of precision optics. This lens is designed for use in a variety of optical systems, offering a high level of performance and precision.

The lens features a symmetric convex-convex design, with both surfaces curved outward. The first surface has a radius of curvature of 34.721 mm, while the second surface has a radius of -34.721 mm. This design results in an effective focal length (EFL) of 30 mm, making it suitable for applications that require a moderate level of magnification.

The lens is made from N-SK2 Schott glass, a high-quality material known for its excellent optical properties. This glass has a refractive index of approximately 1.541 at a wavelength of 587.6 nm, which is within the visible light spectrum. The lens has no coating, which means that it does not have any special surface treatments to enhance its optical properties.

The lens has a thickness of 2 mm at the edge and 9.5 mm at the center. This design ensures that the lens is robust and can withstand the rigors of regular use. The lens is unmounted, giving users the flexibility to integrate it into their optical systems in the most suitable way.

According to the vendor, this lens is currently in stock and can be purchased directly from the Qioptiq Photonics website. The website also provides more detailed specifications and technical data for those who require more in-depth information.
