49-899-INK 15.0mm Dia. x 45.0mm FL; VIS 0deg; Inked; Plano-Convex Lens VIS 0° 425-675nm
This product is a plano-convex lens, type 49-899-INK, offered by Edmund Optics. The lens has a diameter of 15.0mm and a focal length of 45.0mm, making it suitable for a variety of optical applications. The lens is made from the material n-bk7 schott, a common choice for its high refractive index and low dispersion.
The lens features a vis-0 coating on both the front and back surfaces. This coating, standard from Edmund Optics, is designed to improve transmission in the visible spectrum, specifically between 425-675nm. The coating helps to minimize reflection and increase the overall efficiency of the lens.
The geometry of the lens includes a thickness of 1.26mm at the edge and 2.5mm at the center. The inner radius is 0mm, and the outer radius is also 0mm, indicating a flat surface on the uncoated side. The lens's effective focal length (EFL) is 45.0mm, and the back focal length (BFL) is 43.35mm.
The lens's shape is spherical, with a radius of curvature of 23.26mm on the coated side. This shape is common in optical systems due to its ease of manufacturing and the ability to focus light to a point.
