ASL10142M-A 1 in Dia. UVFS High-Precision; CNC Polished Aspheric Lenses; NA=0.143; EFL=79 mm AR 350-700nm
The ASL10142M-A is a high-precision aspheric lens, meticulously crafted by Thorlabs. This lens, designed for use in the UV-FS band, boasts a 1-inch diameter and a focal length of 79 mm. Its asphere surface is CNC polished, ensuring superior optical quality and performance.
The lens is made from UVFS material, identified by the manufacturer as UVFS Mal- 1965. It has a numerical aperture (NA) of 0.143, which is a measure of the lens' light-gathering ability. The lens' geometry includes an inner radius of 0, an outer radius of 0, and a thickness at the edge of 3 mm. The center thickness is 6 mm, and the lens has a refractive index (RI) of 1.4398 at 780 nm.
The ASL10142M-A features a front and back coating of Thorlabs' ASL10142-A, which is an anti-reflective coating designed for use in the 350-700 nm range. This coating enhances the lens' transmission and reduces unwanted reflections, thereby improving overall system performance.
