36-681 9mm Dia x 22mm FL Uncoated; UV Plano-Convex Lens

The 36-681 9mm Dia x 22mm FL Uncoated; UV Plano-Convex Lens is a high-quality optical component sourced from Edmund Optics. This lens, with a diameter of 9mm, is designed for use in a variety of applications that require a spherical lens with a plano-convex geometry and a circular base shape.

The lens features a focal length of 22mm, providing a clear focus for incoming light rays. The edge thickness of the lens is 1.94mm, while the center thickness is 3mm, ensuring structural integrity and minimal distortion. The lens's effective focal length (EFL) is also 22mm, making it suitable for systems where a long focal length is required.

The inner and outer radii of the lens are 0mm, indicating a flat surface on one side and a curved surface on the other. The curvature of the lens (R1) is 10.09mm. The back focal length (BFL) is 19.94mm, which is the distance from the lens's rear surface to its focal point.

This lens is made from fused silica (mal-1965), a material known for its excellent optical properties, including high transmittance across a wide spectrum, making it ideal for UV applications. The lens is uncoated, which means it does not have any additional layers to enhance its optical properties. However, this does not affect its performance in UV applications.

The lens is designed to work with a wavelength of 587.6nm, which is in the visible light spectrum. It is important to note that the lens's performance can vary depending on the wavelength of the light it is intended to focus.
