LB01-12-40 12.7 mm Dia. N-BK7 Double-Convex Lens; EFL=40mm Uncoated
This is a high-quality spherical lens, specifically a double-convex lens, sourced from CeNing Optics. It boasts a 12.7 mm diameter and is made from the renowned N-BK7 glass, a popular choice in the optical industry due to its excellent optical properties. The lens has an effective focal length (EFL) of 40mm, making it suitable for a wide range of applications.
The lens's geometry is characterized by its edge thickness of 2mm and center thickness of 2.99mm. The first radius of curvature (R1) is 41.02mm, while the second radius (R2) is -41.02mm, indicating the double-convex nature of the lens. The inner and outer radii are both 0mm.
The lens is uncoated, meaning it does not have any anti-reflective or other coatings. This may be suitable for applications where such coatings are not required or desired. However, users should be aware that uncoated lenses can suffer from reflective losses, which may affect the performance in high-light applications.
The lens is in stock and available for immediate purchase. For more information, please refer to the vendor's website provided in the item data.
