G313337400 25.4 mm Dia. N-BK7 Double-Concave Lens; EFL=-50mm
This is a G313337400 model double-concave lens, featuring a 25.4 mm diameter and a center thickness of 1.5 mm. The lens is made of N-BK7, a popular glass type in the optical industry, known for its excellent optical properties and versatility. The lens has a negative focal length (EFL) of -50mm, making it suitable for applications that require light convergence.
The lens's geometry is characterized by its two radii of curvature, R1 and R2, which are -52.33mm and 52.33mm respectively. These radii determine the lens's concave shape, which is symmetrical around the center. The lens's inner and outer radii are both zero, indicating that the lens's edges are perpendicular to its central axis.
The lens is coated with Qio Silver RAGV 45 on both the front and back surfaces. This coating enhances the lens's performance by reducing reflection and increasing transmission, making it more efficient in transmitting light.
The lens is sourced from Qioptiq Photonics, a renowned vendor in the optical industry. According to the vendor's website, the lens is in stock, ensuring quick delivery for those who need it.
