67-943 25mm Dia. x 38mm FL; Laser Grade Plano-Convex Lens Laser V-Coat 266nm
The 67-943 is a laser grade plano-convex lens, boasting a diameter of 25mm and a focal length of 38mm, sourced from the reputable vendor Edmund Optics. This lens is designed for use with a wavelength of 266nm, making it suitable for a range of applications that utilize this wavelength.
The lens is constructed from fused silica (mal-1965), a material known for its excellent optical properties, including high transparency and resistance to thermal shock. The front and back surfaces of the lens are coated with edm las v-coat 266, a specialized coating that enhances its performance in laser applications.
The geometry of the lens is characterized by its diameter, thickness edge, and thickness center. The diameter is 25mm, while the thickness edge is 1.96mm and the thickness center is 7.25mm. The lens's effective focal length (EFL) is 38mm, and its radius of curvature (R1) is 17.42mm. The back focal length (BFL) is 33.03mm, and both the inner and outer radii are 0mm.
This lens is a spherical lens, meaning it has a curved surface that is a portion of a sphere. The plano-convex design features one flat surface and one curved surface, which focuses the light onto a single point. This design is often used in laser applications due to its ability to focus light efficiently.
