ASL10142M-C 1 in Dia. UVFS High-Precision; CNC Polished Aspheric Lenses; NA=0.143; EFL=79 mm AR 1050-1700nm
The ASL10142M-C is a high-precision aspheric lens, meticulously crafted by Thorlabs. This lens, with a diameter of 1 inch, is made from UVFS material, specifically UVFS mal- 1965. It is designed to operate at a wavelength of 780 nm, making it suitable for a wide range of applications.
The lens boasts an effective focal length (EFL) of 79 mm, which is a crucial factor in determining the lens's magnification power. The EFL, combined with the lens's numerical aperture (NA) of 0.143, ensures excellent image quality and light gathering capability.
The ASL10142M-C features a sophisticated aspheric design, which is CNC polished to perfection. This design significantly reduces spherical aberration, a common issue in traditional lenses, thereby improving optical performance. The lens's geometry includes an inner radius of 0, an outer radius of 0, a thickness at the edge of 3 mm, and a thickness at the center of 6 mm.
The lens is coated with a specialized anti-reflective coating, THo ASL10142-C, on both the front and back surfaces. This coating is designed to reduce surface reflections and increase transmission in the 1050-1700 nm range, making the lens even more efficient in its function.
