ASL10142-532 1 in Dia. UVFS High-Precision; CNC Polished Aspheric Lenses; NA=0.145; EFL=77.8mm 532nm V Coat
The ASL10142-532 is a high-precision aspheric lens, meticulously crafted by Thorlabs. This lens is designed for use with a wavelength of 780nm, offering a numerical aperture (NA) of 0.145, ensuring high-quality imaging and light transmission.
The lens is made from UVFS material, identified as UVFS Mal- 1965, which is known for its excellent optical properties. The lens features a circular base shape with a diameter of 1 inch (25.4mm) and a thickness of 3.5mm at the edge, providing robustness and stability. The center thickness is 6mm, ensuring the lens maintains its shape under various conditions.
The ASL10142-532 boasts an effective focal length (EFL) of 77.8mm, making it suitable for a wide range of optical applications. The lens's aspheric design, characterized by radii of curvature r1 and r2 of 35.8256mm and 0mm respectively, helps minimize spherical aberration, enhancing the quality of the optical system.
The lens's front and back surfaces are coated with a V Coat, specifically designed for the 532nm wavelength. This coating improves light transmission and reduces reflection, further enhancing the lens's performance.
