69-678 25mm Dia. x 75mm FL; Uncoated; Si Plano-Convex Lens
The 69-678 is a 25mm diameter, 75mm focal length plano-convex lens, sourced from Edmund Optics. This lens is made of silicon, specifically silicon sal vil 1957, and is uncoated. The lens's geometry includes a 2.57mm edge thickness and a 3mm center thickness, with a 74.12mm back focal length and an 181.32mm radius of curvature.
The lens is designed for use with a wavelength of 10600nm and features a spherical shape. The uncoated nature of the lens means it does not have any additional layers to alter its light transmission properties. This can be beneficial in certain applications where minimal reflection and dispersion are required.
Please note that the lens's inner and outer radii are both zero, indicating a flat surface on one side and a curved surface on the other. This design is typical of plano-convex lenses, which are often used to focus light in various optical systems.
The lens's current status is in stock, according to the vendor's website. For more detailed information, you can refer to the provided weblink.
