G314321331 25.4 mm Dia. N-BK7 Plano-Concave Lens; EFL=-50mm
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 -50mm, 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, which is typical for plano-concave lenses. The lens's coating is Qio AR/RALVIS AOI 45 on both the front and back surfaces, providing anti-reflective properties and increasing light transmission.
This lens is designed to work at a wavelength of 588 nm, making it suitable for applications that use this wavelength. The lens's shape is spherical, a common shape for optical lenses due to its ease of manufacturing and good optical performance.
The lens is currently in stock and can be purchased from the Qioptiq Photonics website. For more information, please refer to the provided weblink.
