48-690 6mm Dia. x -15 FL; VIS 0deg Coated; Plano-Concave Lens 425-675nm
The 48-690 is a 6mm diameter Plano-Concave lens with a focal length of -15, sourced from Edmund Optics. This lens is designed for use within the wavelength range of 425-675nm, making it suitable for a wide array of optical applications.
The lens is fabricated from the high-quality material, n-BK7 Schott, which is renowned for its excellent optical properties and durability. The base shape of the lens is circular, and it features a geometry that includes a 2.49mm thickness at the edge and a 2mm thickness at the center.
The 48-690 is coated with 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 improving transmission within the visible spectrum.
The lens's inner and outer radii are both zero, indicating a simple, straightforward design that is easy to integrate into optical systems. The base shape, spherical, is a common choice for many optical applications due to its ease of manufacturing and versatility.
