69-674 25mm Dia. x 30mm FL; Uncoated; Si Plano-Convex Lens
The 69-674 is a 25mm diameter, 30mm focal length plano-convex lens, sourced from Edmund Optics. This lens is made of silicon, specifically silicon sal vil 1957, and does not have any coating.
The lens's geometry is characterized by a 2.41mm thickness at the edge, increasing to 3.5mm at the center. The effective focal length (EFL) is 30mm, and the radius of curvature (R1) is 72.53mm. The back focal length (BFL) is 28.98mm, and both the inner and outer radii are 0mm.
This lens is designed for use with a wavelength of 10600nm, and its spherical shape makes it suitable for a wide range of optical applications. The uncoated surface allows for greater customization, as users can apply their own coatings to suit their specific needs.
Please note that the lens is currently in stock, according to the vendor's website. For more information, including pricing and availability, please refer to the provided weblink.
