G313375331 12.7 mm Dia. N-BK7 Double-Concave Lens; EFL=-100mm

This is a G313375331 12.7 mm diameter N-BK7 double-concave lens, with a focal length (EFL) of -100mm, sourced from Qioptiq Photonics. The lens is designed for use in a variety of optical systems, offering high-quality performance and precision.

The lens is made from N-BK7 glass, a popular choice in the optical industry due to its excellent optical properties and high damage threshold. The double-concave design, characterized by two concave surfaces, provides a negative focal length, making it suitable for use in imaging systems where a reduced image size is desired.

The lens has a diameter of 12.7mm and a center thickness of 1.5mm, providing a compact and robust design. The inner and outer radii are 0mm, indicating a symmetrical design, which can help to minimize optical aberrations.

The lens is coated with Qio AL RALVIS AOI 45 on both the front and back surfaces. This anti-reflection coating is designed to reduce surface reflections, improving transmission and enhancing overall system performance.

The lens is available from Qioptiq Photonics, and the provided weblink indicates that it is currently in stock. This makes it a readily available option for those looking to incorporate a high-quality, double-concave lens into their optical systems.
