G063070400 22.4 mm Dia. N-BK7 Mounted Plano-Concave Lens; EFL=-40mm
This is a G063070400 22.4 mm Dia. N-BK7 Mounted Plano-Concave Lens, with a focal length (EFL) of -40mm. The lens is sourced from Qioptiq Photonics, a renowned vendor in the field of precision optics.
The lens is spherical in shape, with a base shape of a circle. It has a diameter of 22.4mm and a center thickness of 1.5mm. The inner and outer radii are both zero, indicating a plano-concave design. The focal length of -40mm suggests that this lens will diverge light, making it suitable for applications such as beam expansion or collimation.
The lens is made of N-BK7, a popular glass type known for its excellent optical properties. This material is often used in high-precision optical systems due to its low dispersion and high transmission in the visible spectrum. The lens is coated with Qio Silver RAGV 45 on both the front and back surfaces, which enhances its light-gathering capabilities and durability.
The item data also indicates that this lens is mounted, suggesting that it is ready for immediate use in optical systems. The web link provided in the item data indicates that the lens is currently in stock, making it readily available for purchase.
