This is a Plano-Convex Lens, sourced from the renowned optical components vendor, Edmund Optics. The lens is designed for the visible spectrum, specifically for wavelengths between 425nm and 675nm, making it suitable for a wide range of optical applications.
The lens has a diameter of 12.7mm and a focal length of 15.0mm, as indicated by its designation. The geometry of the lens includes a thickness of 1.94mm at the edge and 5.25mm at the center. The lens's effective focal length (EFL) is also 15.0mm, and the radius of curvature (R1) is 7.75mm. The back focal length (BFL) is 11.53mm.
The lens is made from N-BK7 Schott, a popular optical glass due to its excellent optical properties and relatively low cost. The lens's surfaces are coated with the EDM VIS-0 standard curve coating on both the front and back, which enhances its transmission capabilities within the specified wavelength range.
