38-478-INK 35.0mm Dia. x 35.0mm FL; VIS-EXT; Inked; Plano-Convex Lens VIS-EXT 350-700nm

The 38-478-INK is a Plano-Convex lens, a type of spherical lens with a flat surface on one side and a curved surface on the other. This particular model has a diameter of 35.0mm and a focal length of 35.0mm, making it suitable for a wide range of optical applications.

The lens is made from n-sf11 Schott, a high-index glass that offers excellent optical performance. The high refractive index of this material allows for a more compact lens design, making it an ideal choice for space-constrained applications.

The lens features a VIS-EXT coating on both the front and back surfaces. This coating is designed to extend the visible range of the lens, making it suitable for use in applications where a broad spectrum of light needs to be transmitted. The coating also helps to reduce surface reflections, improving the overall efficiency of the optical system.

The lens has an outer radius of 0mm and an inner radius of 0mm, indicating that it is a simple, single-element lens. The thickness at the edge of the lens is 1.7mm, while the thickness at the center is 8mm. The back focal length (BFL) of the lens is 30.52mm, and the effective focal length (EFL) is 35mm.

This lens is inked, indicating that it has been marked or labeled in some way. This could be for identification purposes or to indicate specific properties or characteristics of the lens.

The lens is sourced from Edmund Optics, a leading supplier of optical components. According to the vendor, the lens is currently in stock, making it readily available for immediate use.
