The PFS Spectrographs are integrated and validated their performances at Laboratoire d’Astrophysique de Marseille (LAM), France. At present, the first spectroraph module is being assembled, tested for the performance of individual parts. Last month, we had the First Light of the visible-red camera in the laboratory.
The below is the first light image, in which you can see many spectra of fibers illuminated by ambient light.
Hereafter, image qualities such as spot size and its stability will be tested using engineering fibers and designated light source.
