47-344 25.0mm Dia. x 35.0mm FL; VIS 0deg Coated; Plano-Convex Lens VIS 0° 425-675nm

This product is a Plano-Convex Lens, sourced from the renowned optical components vendor, Edmund Optics. The lens, identified as 47-344, boasts a diameter of 25.0mm and a focal length of 35.0mm, making it a versatile choice for various optical applications.

The lens is crafted from the high-quality material, N-BK7 Schott, a borosilicate crown glass known for its excellent optical properties. This material ensures high transmission in the visible spectrum, making it suitable for applications involving visible light.

The lens features a standard coating, specifically the EDM VIS-0 STD curve, on both the front and back surfaces. This coating enhances the lens's performance by reducing surface reflections and increasing transmission, thereby improving the overall efficiency of the optical system.

The geometry of the lens includes a thickness of 2mm at the edge and 7.01mm at the center. The inner and outer radii are 0mm, and the lens has a base shape of a circle. The radius of curvature (R1) is 18.11mm, and the back focal length (BFL) is 30.42mm.

The lens is designed to operate at a wavelength of 587.6nm, which falls within the visible spectrum. The EFL (Effective Focal Length) of the lens is 35mm, a critical parameter for determining the lens's magnification power.
