G313374000 12.7 mm Dia. N-BK7 Double-Concave Lens; EFL=-50mm Uncoated
The G313374000 is a high-quality double-concave lens, boasting a 12.7 mm diameter and a center thickness of 1.5 mm. This lens is crafted from N-BK7, a popular optical glass from Schott, renowned for its excellent optical properties. The lens's concave-concave base shape, combined with its inner and outer radii of 0, contributes to its double-concave design.
The lens's effective focal length (EFL) is -50mm, indicating that it is a diverging lens, causing incoming light rays to spread out. This makes it ideal for applications such as beam expansion or collimation. The lens is uncoated, offering a cost-effective solution for applications where anti-reflection coatings are not required.
This lens is sourced from Qioptiq Photonics, a leading global designer and manufacturer of photonic products and solutions.
