(a) Parameters of the designed focusing achromatic cylindrical lens. The compound lens consists of an LAKN22 lens (n1) and an SF10 lens (n2). The LAKN22 lens has a center thickness of 4 mm and two surface curvatures of 121 mm (R1) and −99.7 mm (R2). The SF10 lens has a center thickness of 4 mm and two surface curvatures of −99.7 mm (R2) and −1600 mm (R3). (b) Chromatic focal shift in units of Rayleigh range (307 mm). Black curve is the performance of a single-element cylindrical lens (Thorlabs LJ1653L1), which has a similar focal length as the designed lens. Red curve is the performance of the designed achromatic cylindrical lens.
