Paper Abstract

GUIELOA is a Curvature type Adaptive Optics system for the 2.1 m San Pedro Martir Telescope. It performs a bimorph 19 actuators deformable mirror and a 19 lens-let array for the wave-front sensor (WFS). GUIELOA corrects effectively the first 8 Zernike polynomials of the aberrated wave-front produced by the atmospheric turbulence. For the closed loop control it performs two SPARC FORCE 5 SBC computers working in concert. The lens-let array + optical fibers send the light from defocused pupil images to 19 avalanche photo-diodes. In this work it is shown how the lens-let array was manufactured at IAUNAM with CIDESI and Centro de Investigaciones en Optica (CIO).
