45-161 25mm Dia. x 35mm FL Uncoated; Double-Convex Lens
The 45-161 is a 25mm diameter, 35mm focal length uncoated double-convex lens, sourced from the renowned optical vendor, Edmund Optics. This lens is a spherical lens with a convex-convex base shape, contributing to its double-convex nature.
The lens's geometry is characterized by a diameter of 25mm, with an edge thickness of 2mm and a center thickness of 6.6mm. The effective focal length (EFL) is 35mm, and the radii of curvature are 35.09mm for the first surface and -35.09mm for the second surface. The back focal length (BFL) is 32.81mm. The lens's inner and outer radii are both zero, indicating a uniform curvature across the lens surface.
The lens is made of n-BK7 Schott, a high-quality optical glass known for its excellent transparency and low dispersion. The wavelength for this lens is 587.6nm. The lens is uncoated, meaning it does not have any anti-reflective or other surface coatings.
