AL50100-A 50 mm Dia. S-LAH64 High-Precision; CNC Polished Aspheric Lenses; EFL=100 mm; NA=0.24 AR 350-700nm
The AL50100-A is a high-precision aspheric lens offered by Thorlabs, a leading vendor in the optical industry. This lens, with a diameter of 50 mm, is designed for use with a wavelength of 780 nm and features an effective focal length (EFL) of 100 mm and a numerical aperture (NA) of 0.24.
The lens is made from n-BK7 Schott, a high-quality optical glass, and its aspheric shape is achieved through CNC polishing, ensuring high precision and accuracy. The lens's geometry includes an inner radius of 0, an outer radius of 0, a thickness at the edge of 3.8 mm, and a thickness at the center of 10 mm.
The lens's front and back surfaces are coated with a broadband anti-reflection coating (AR) that covers the spectrum from 350 to 700 nm, further enhancing its performance in a wide range of applications. The lens's detailed specifications, including its conic constant (k1) of -0.575, as well as its higher-order aspheric coefficients (a2, a4, a6, a8, a10, a12, and a14), are all provided, allowing for a thorough understanding of its optical properties.
