Abstract
In the frame of the MACAO projects, a fibre-bundle was developed to feed 60 Avalanche Photodiodes. The optical split between the channels is done by a train of lenslets; one of it is the result of the laser-writing technology pushed beyond its conventional limits. This paper describes some of the measuring devices we developed to control the performances of the prototypes which were delivered last two years. The final performances of the lenslets are assessed, diffraction-limited optics with short focal lengths (<50mm) for diameter up to more than 3 mm.
