G314323331 25.4 mm Dia. N-BK7 Plano-Concave Lens; EFL=-200mm

This is a Plano-Concave lens with a diameter of 25.4 mm, 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 1.5 mm and an effective focal length (EFL) of -200mm, making it suitable for applications that require a concave lens.

The lens's geometry includes an inner radius of 0 mm and an outer radius of 0 mm, indicating a plano surface on one side and a concave surface on the other. The concave surface has a radius of curvature of -104.41 mm.

The lens is designed to operate at a wavelength of 588 nm. It comes with a front and back coating of Qio AR Ralvis AOI 45, which is a broadband anti-reflection coating, designed to reduce surface reflections and increase transmission.

This lens is a spherical lens, which means it has a spherical surface, common in many optical systems due to its ease of manufacturing and good optical performance.

The lens is currently in stock and available for purchase on the Qioptiq Photonics website.
