AL1210-B 12.5 mm Dia. S-LAH64 High-Precision; CNC Polished Aspheric Lenses; EFL=10 mm; NA=0.55 AR 650-1050nm
The AL1210-B is a high-precision aspheric lens offered by Thorlabs, a leading global manufacturer of photonics equipment. This lens, crafted from S-LAH64 Ohara, boasts a 12.5 mm diameter and a 1.6 mm thickness at the edge, with a center thickness of 4.3 mm. The lens's design includes an inner radius of 0 mm and an outer radius of 0 mm, making it a circular component.
The lens's geometry is defined by its effective focal length (EFL) of 10 mm and a numerical aperture (NA) of 0.55. The aspheric surface is defined by a series of aspheric coefficients, including k1 (-1), k2 (0), a2 front (0), a4 front (9.8464319e-05), a6 front (-6.9905851e-08), a8 front (-2.3874994e-09), a10 front (-1.1328583e-11), and a12 front (8.7255438e-14), a14 front (2.8967313e-16), a16 front (1.7632112e-18).
The lens features anti-reflection coatings on both the front and back surfaces, designed to minimize reflection across the 650-1050 nm wavelength range. This lens is part of Thorlabs' extensive catalog, which includes a wide variety of optical elements, and is currently in stock, according to the vendor's website.
