69-676 25mm Dia. x 40mm FL; Uncoated; Si Plano-Convex Lens
The 69-676 is a 25mm diameter, 40mm 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 diameter of 25mm, a thickness at the edge of 2.19mm, and a center thickness of 3mm. The effective focal length (EFL) is 40mm, and the radius of curvature (R1) is 96.7mm. The back focal length (BFL) is 39.12mm, and both the inner and outer radii are 0mm.
This lens is designed for use with a wavelength of 10600nm, and its shape is spherical. The lack of coating on this lens means that it will not have any additional protection or enhancement for its optical properties.
