G311381000 12.7 mm Dia. N-BK7 Double-Convex Lens; EFL=15mm Uncoated
This is a G311381000 12.7 mm Dia. N-BK7 Double-Convex Lens, characterized by a focal length (EFL) of 15mm and uncoated surfaces. The lens is sourced from Qioptiq Photonics, a renowned vendor in the field of precision optics.
The lens is of the Spherical type, specifically a Symmetric-Convex Lens (Convex-Convex), and has a base shape of Circular. The geometry of the lens includes a diameter of 12.7mm, a thickness at the edge of 1.1mm, and a thickness at the center of 4mm. The inner and outer radii are both 0, indicating a symmetrical design.
The lens is made from N-BK7, a popular glass type in the optical industry, known for its excellent optical properties. The wavelength of 587.6nm suggests this lens is designed for use in the visible light spectrum.
The lens is uncoated, meaning it does not have any anti-reflective or other coatings applied to its surfaces. This may result in higher reflective losses and a lower overall transmission compared to coated lenses. However, uncoated lenses are often more cost-effective and can be suitable for many applications.
The lens is currently in stock and available for purchase through the vendor's website. For more information, please refer to the provided weblink.
