110-0218E 25.4 mm Dia. x 90 mm FL; Uncoated; Plano-Convex Lens
The 110-0218E is a Plano-Convex lens with a diameter of 25.4 mm and a focal length of 90 mm. This lens is sourced from EKSMA Optics, a reputable vendor known for their high-quality optical components. The lens is made of BK7 Schott, a popular glass type in the optical industry due to its excellent optical properties and versatility.
The lens's geometry is characterized by its plano-convex shape, where one side is flat (plano) and the other side is curved (convex). The thickness at the edge of the lens is 2 mm, while the center thickness is 3.8 mm. The lens's effective focal length (EFL) is 90 mm, which is the distance from the lens's principal point to the focal point.
The lens's inner and outer radii are both 0, indicating that the curved surface is a portion of a sphere with an infinite radius. This is consistent with the plano-convex shape, where the curved surface is typically a small portion of a large sphere.
The lens is uncoated, meaning it does not have any anti-reflective or other coatings. While coatings can enhance the lens's performance in certain applications, an uncoated lens can be suitable for applications where such enhancements are not required.
The lens is designed to work at a wavelength of 546 nm. This wavelength falls within the visible light spectrum, making this lens suitable for applications involving visible light.
