This is a G063060000 22.4 mm Dia. N-BK7 Mounted Double-Concave Lens, a high-quality optical component sourced from Qioptiq Photonics. The lens, which is uncoated, has a double-concave structure with a center thickness of 1.5 mm and a effective focal length (EFL) of -40 mm, making it suitable for a wide range of optical applications.
The lens is made from N-BK7, a popular borosilicate glass known for its excellent optical properties. The base shape of the lens is circular, and it has an outer diameter of 22.4 mm. The inner and outer radii of the lens are 0, indicating a symmetrical concave-concave geometry. The first radius of curvature (R1) is -41.867 mm, and the second radius of curvature (R2) is 41.867 mm.
This lens is designed to operate at a wavelength of 588 nm. The shape of the lens is spherical, which is a common choice for many optical systems due to its simplicity and wide range of applications. The lens does not come with any coating, which means it is in its raw state and users may need to apply their own coatings based on their specific requirements.
The lens is readily available and in stock, as indicated by the "weblink status" field. For more information, users can refer to the vendor's website through the provided weblink.
