Perfect Dia:18.0 mm N-BK7 Plano-Convex Lens; EFL=20.0 mm Perfect Transmission
This is a high-quality Plano-Convex lens from the renowned vendor 3DOptix. The lens, which is spherical in shape, has a base shape of a circle and is designed for perfect transmission. The lens is made from N-BK7, a popular optical glass from Schott, known for its excellent optical properties.
The lens has a diameter of 18.0 mm and a thickness at the edge of 1.8 mm. The center thickness is 7.1 mm, providing a robust structure for various applications. The Effective Focal Length (EFL) of this lens is 20.0 mm, making it suitable for applications that require a longer focal length.
The lens's front and back surfaces are coated with 3DO per transmission coating, ensuring optimal light transmission and minimal reflection. The radius of curvature for the first surface (R1) is 10.3 mm, and the back focal length (BFL) is 15.3 mm. The lens does not have an inner radius, and the outer radius is also 0, indicating a uniform curvature.
