G314334400 12.7 mm Dia. N-BK7 Plano-Concave Lens; EFL=-200mm
This is a Plano-Concave lens with a diameter of 12.7 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 (R1) of -102.92 mm.
The lens is coated with Qio Silver RAGV 45 on both the front and back surfaces, which is a broadband anti-reflection coating designed to reduce surface reflections and improve transmission. The coating is optimized for a wavelength of 588 nm.
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 variety of applications due to their simplicity and availability.
The lens is currently in stock and available for purchase on the Qioptiq Photonics website. For more information, please refer to the provided weblink.
