AL3026-B 30 mm Dia. S-LAH64 High-Precision; CNC Polished Aspheric Lenses; EFL=26 mm; NA=0.52 AR 650-1050nm
The AL3026-B is a high-precision aspheric lens, meticulously crafted by Thorlabs. This lens, designed for use in the 780nm wavelength range, is constructed from S-LAH64, a material from Ohara. The lens boasts a diameter of 30 mm and a thickness of 3.9 mm at the edge, with a center thickness of 9.7 mm.
The lens's design includes an effective focal length (EFL) of 26 mm, an inner radius of 0 mm, and an outer radius of 0 mm. The aspheric surface is defined by a series of coefficients, including k1 (-1), k2 (0), a2 front (0), a4 front (5.4144542e-06), a6 front (-8.0413315e-10), a8 front (-2.9871189e-12), a10 front (-1.4917927e-15), and a12 front (1.3777317e-18), a14 front (4.4258023e-21), a16 front (-3.4927668e-24).
The lens features a high numerical aperture (NA) of 0.52, enhancing its light-gathering capabilities. The front and back surfaces of the lens are coated with THo BBAR, ensuring optimal performance in the 650-1050nm wavelength range. The lens's shape is aspheric, providing superior image quality compared to traditional spherical lenses.
