G063060525 22.4 mm Dia. N-BK7 Mounted Double-Concave Lens; EFL=-40mm 725-1050nm
This is a G063060525 model double-concave lens, featuring a 22.4 mm diameter and a center thickness of 1.5 mm. The lens is made of N-BK7, a popular optical glass from Schott, known for its excellent optical properties and wide transparency range.
The lens has a negative focal length (EFL) of -40mm, making it a concave lens. It is designed to diverge light, which is useful in various optical applications such as beam expanders, collimators, and objective lenses.
The lens is coated with Qio Bbar Arb2nirnbk7 on both the front and back surfaces, providing broadband anti-reflection properties in the 725-1050nm wavelength range. This coating reduces surface reflections, enhancing the lens's transmission and overall performance.
The lens is spherical in shape, meaning it has a continuously curving surface. The radii of curvature for the first and second surfaces are -41.867mm and 41.867mm respectively. The lens is mounted, indicating it is ready for immediate use in optical systems.
This lens is available from Qioptiq Photonics, a leading vendor in the field of precision optics. According to the vendor's information, the lens is in stock, ensuring quick delivery.
