47-899 15mm Dia. x 30mm FL; VIS 0deg Coated; Double-Convex Lens VIS 0deg 425-675nm
The 47-899 is a double-convex lens, characterized by its circular base shape and spherical geometry. This lens, sourced from Edmund Optics, boasts a diameter of 15mm and a focal length of 30mm, making it a versatile choice for various optical applications.
The lens's geometry is further defined by its inner and outer radii, both of which are 0mm, and its thickness at the edge and center, measuring 2.13mm and 4mm respectively. The effective focal length (EFL) is 28.82mm, while the radii of curvature (R1 and R2) are 30.5mm and -30.5mm respectively.
The lens is crafted from n-BK7 Schott, a popular optical glass known for its excellent transparency and low dispersion. This material is particularly suitable for applications in the visible spectrum, as evidenced by the lens's wavelength of 587.6nm.
The 47-899 is coated with the EDM VIS-0 STD curve on both the front and back surfaces. This coating enhances the lens's performance in the visible spectrum, specifically within the 425-675nm range.
