This is the G314315000 22.4 mm Dia. N-BK7 Plano-Concave Lens, a high-quality optical component sourced from Qioptiq Photonics. The lens, which is uncoated, has a diameter of 22.4 mm and a center thickness of 1.5 mm. It features a negative focal length (EFL) of -50 mm, making it suitable for a wide range of optical applications.
The lens is made of N-BK7, a popular borosilicate glass known for its excellent optical properties. This material is often used in high-precision optical systems due to its low coefficient of thermal expansion and high transmittance in the visible and near-infrared regions. The lens's base shape is circular, and its geometry includes a plano-concave design with an inner radius of 0 and an outer radius of 0.
The lens is designed to operate at a wavelength of 588 nm. It has a spherical shape, which is a common choice for optical components due to its ease of manufacturing and high optical quality. The lens's coating is listed as '{}' in the item data, indicating that it is uncoated. This may affect its performance in certain applications, particularly those requiring high transmission or resistance to environmental factors.
