ASL10142 1 in Dia. UVFS High-Precision; CNC Polished Aspheric Lenses; NA=0.143; EFL=79 mm Uncoated

The ASL10142 is a high-precision aspheric lens offered by Thorlabs, designed for use in applications that require superior optical performance. This lens is made from UVFS material with a catalog number of ASL10142, and it is uncoated. The lens is available for purchase directly from Thorlabs' website, and as of the time of data collection, it is in stock.

The ASL10142 has a diameter of 1 inch (25.4 mm) and a thickness at the edge of 3.5 mm. The effective focal length (EFL) of this lens is 79 mm, and it has a numerical aperture (NA) of 0.143. The lens's geometry includes an inner radius of 0 mm, an outer radius of 0 mm, and a thickness at the center of 6 mm.

The aspheric shape of this lens is defined by its conic constant (k1) of -0.6291, and its aspheric coefficients (a2, a4, a6, a8, a10, a12, a14, a16) are -0, 1.4398e-07, 0, 0, 0, 0, 0, 0 respectively. These coefficients are used to calculate the surface sagitta of the lens, which is the perpendicular distance from a point on the lens surface to the lens's optical axis.

Please note that the ASL10142 does not come with any coating. Coatings can be used to reduce surface reflections, increase transmission, or provide other benefits, depending on the specific application. If you require a coated lens, Thorlabs offers a variety of coating options that can be added to this lens.
