24-070 25mm Dia. Fused Silica Precision Laser Aspheric Lens; EFL=100mm; NA=0.125 Uncoated

This is the 24-070 25mm Dia. Fused Silica Precision Laser Aspheric Lens, a high-quality optical component designed for use in laser applications. The lens, sourced from the reputable vendor Edmund Optics, boasts a catalog number of 24-070 and is currently in stock, as indicated by its weblink status.

The lens is of the aspheric type, featuring a base shape of a circle and a material ID of fused sil mal-1965. It is designed to operate at a wavelength of 355nm. The geometry of the lens is precisely defined, with an inner radius of 0, an outer radius of 0, a diameter of 25mm, and a thickness at the edge of 3.85mm. The effective focal length (EFL) is 100mm, and the lens has an NA (numerical aperture) of 0.125.

The lens is uncoated, a feature that can be beneficial in certain applications where the natural properties of the material are desired. The front diameter is 0mm, with an extremely small eccentricity (e front) of 1.077002e-07, indicating a high degree of symmetry and precision. The lens's front face has a radius of curvature (r1) of 47.609, with the second radius (r2) being 0. The back focal length (bfl) is 96.3mm, and the thickness at the center is 6mm.

The lens's conic constant (k1) is -0.67, and all other aspheric terms (k2, d front, e front, f front, g front, h front, j front, l front) are 0, indicating a simple aspheric surface. This lens is a precise, high-quality component suitable for various laser applications.
