LB01-12-30 12.7 mm Dia. N-BK7 Double-Convex Lens; EFL=30mm Uncoated
This is a high-quality spherical lens, specifically a double-convex lens, sourced from CeNing Optics. The lens has a circular base shape and is designed for use in a wide range of optical applications.
The lens has a diameter of 12.7 mm and a thickness at the edge of 2 mm. The center thickness is slightly greater at 3.33 mm. The effective focal length (EFL) of this lens is 30 mm. The first radius of curvature (R1) is 30.55 mm, while the second radius of curvature (R2) is -30.55 mm, indicating the double-convex nature of the lens.
The lens is made from n-BK7, a popular optical glass from Schott. This material is known for its excellent optical properties, making it a common choice for many applications. The lens is uncoated, meaning it does not have any additional layers to enhance its optical properties or protect it from environmental factors.
The lens is designed to work with light of a wavelength of 546.1 nm. This wavelength falls within the visible light spectrum, suggesting that this lens is suitable for use in applications involving visible light.
