G063059331 22.4 mm Dia. N-BK7 Mounted Double-Concave Lens; EFL=-30mm
This is a G063059331 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 versatility. The effective focal length (EFL) of this lens is -30mm, making it a concave lens that diverges light.
The lens's geometry includes two radii of curvature, R1 and R2, which are -31.396mm and 31.396mm respectively. These radii determine the lens's concave shape, which is symmetrical around the center. The lens's inner and outer radii are both 0, indicating that the lens's edges are perpendicular to the optical axis.
The lens is coated with Qio AL RALVIS AOI 45 on both the front and back surfaces. This coating enhances the lens's performance by reducing reflection and increasing transmission, particularly at the wavelength of 588nm.
This lens is sourced from Qioptiq Photonics, a leading vendor in the field of precision optics. According to the vendor's information, the lens is in stock and available for immediate purchase.
