This 34-163 25mm Dia. x 50mm FL UV Plano-Convex Lens, offered by Edmund Optics, is a high-quality optical component designed for use in laser applications at a wavelength of 1550nm. The lens is spherical in shape, specifically a Plano-Convex lens, which means it has one flat (plano) surface and one curved (convex) surface.
The lens boasts a diameter of 25mm and a focal length of 50mm, making it suitable for a wide range of applications. The edge thickness of the lens is 2.13mm, while the center thickness is 5.84mm, providing a solid and durable structure. The lens's effective focal length (EFL) is also 50mm, and the radius of curvature (R1) of the curved surface is 22.92mm. The back focal length (BFL) is 46mm, and both the inner and outer radii are 0mm.
The lens is made from fused silica material, specifically identified as fused sil mal-1965 in the item data. This material is known for its excellent optical properties, making it ideal for use in laser applications. The lens is coated with Edmund Optics' Laser V-Coat 1550, which is applied to both the front and back surfaces. This coating enhances the lens's performance in laser applications, providing improved transmission and reduced reflection.
