G314316400 22.4 mm Dia. N-BK7 Plano-Concave Lens; EFL=-100mm
This is a Plano-Concave lens with a diameter of 22.4 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 -100mm, making it suitable for applications that require a negative focal length.
The lens's curvature is defined by a radius of -52.33 mm on the concave side. The inner and outer radii are 0 mm, indicating that the lens's curved surface faces inward. This lens is unmounted, providing flexibility for users to integrate it into their optical systems according to their specific requirements.
The lens is coated with Qio Silver RAGV 45 on both the front and back surfaces. This coating enhances the lens's performance by reducing reflection and increasing transmission, making it suitable for various applications, including imaging and laser systems.
The lens's geometry is spherical, a common shape in optical lenses due to its ease of manufacturing and good optical performance. The lens is designed to operate at a wavelength of 588 nm.
