ASL10142M 1 in Dia. UVFS High-Precision; CNC Polished Aspheric Lenses; NA=0.143; EFL=79 mm Uncoated
The ASL10142M is a high-precision aspheric lens, meticulously crafted by Thorlabs. This lens, designed for use with a wavelength of 780 nm, is made from UVFS material, specifically identified as UVFS Mal-1965. The lens boasts a diameter of 1 in (25.4 mm) and a thickness of 3 mm at the edge, while the center thickness measures 6 mm.
The lens's geometry is intricately designed with an inner radius of 0 and an outer radius of 0, reflecting its aspheric nature. The effective focal length (EFL) is 79 mm, and the numerical aperture (NA) is 0.143. The lens's first radius of curvature (R1) is 35.8256, and the second radius of curvature (R2) is 0, further emphasizing its aspheric shape.
The lens's aspheric coefficients are as follows: k1 is -0.6291, a2 front is 0, a4 front is 1.4398e-07, a6 front is 0, a8 front is 0, a10 front is 0, and a12 front, a14 front, and a16 front are all 0. These coefficients contribute to the lens's unique optical properties.
The lens does not come with any coating, as indicated in the item data. However, it is CNC polished, ensuring a high level of precision and quality. The lens's catalog number is ASL10142M, and it is currently in stock, as per the vendor's website.
