AL3026 30 mm Dia. S-LAH64 High-Precision; CNC Polished Aspheric Lenses; EFL=26 mm; NA=0.52 Uncoated
The AL3026 is a high-precision aspheric lens offered by Thorlabs, designed with a 30 mm diameter and a focal length of 26 mm. This lens is crafted from S-LAH64 Ohara, a high-refractive index material, and features a CNC-polished surface for superior optical performance.
The lens's aspheric design boasts a base shape of a circle, with an inner radius of 0 mm and an outer radius of 0 mm. The edge thickness is 3.9 mm, while the center thickness is 9.7 mm. The lens's geometry includes a conic constant of -1 and aspheric coefficients up to the 16th order, ensuring high-quality imaging and minimal spherical aberration.
The lens's numerical aperture (NA) is 0.52, indicating a wide acceptance angle and excellent light-gathering capabilities. Notably, this lens is uncoated, providing a clear, unaltered view of the light spectrum at the specified wavelength of 780 nm.
The AL3026 is available for purchase through the Thorlabs website, with the current status indicating it is in stock. This lens is an excellent choice for applications requiring high-precision, aspheric optics, particularly those involving infrared light.
