G314001331 6 mm Dia. N-BK7 Plano-Concave Lens; EFL=-6mm

This is a Plano-Concave lens with a 6 mm diameter, sourced from Qioptiq Photonics. The lens is made of N-BK7, a popular glass type in the optical industry, known for its excellent optical properties and versatility. The lens has a center thickness of 0.5 mm and an effective focal length (EFL) of -6 mm, making it a diverging lens.

The lens's geometry includes a radius of curvature (R1) of -3.101 mm for the concave surface. The inner and outer radii are 0 mm, indicating that the lens has a flat outer surface. This lens is designed to be used at a wavelength of 588 nm.

The lens is coated with Qio AR Al RALVIS AOI 45 on both the front and back surfaces. This anti-reflection coating reduces reflection and increases transmission, enhancing the lens's performance in its intended application.

This lens is a spherical lens, meaning it has a spherical surface. Spherical lenses are the most common type of lens and are used in a wide range of applications due to their simple design and manufacturing process.

The lens is unmounted, providing flexibility for users to mount it according to their specific requirements. The vendor, Qioptiq Photonics, indicates that this item is in stock on their website, ensuring quick delivery for your optical component needs.
