  • Perforated disk for selecting light for an optical imaging
    Patent number: 11802761
    Abstract: Described is a perforated disk for selecting light for an optical imaging, in particular for an optical imaging in a confocal imaging system. The described perforated disk has an optically absorbing material, which has an absorption coefficient of at least 98%, wherein in the optically absorbing material at least one opening is present, which defines an optical passage through the perforated disk. Preferably, the optically absorbing material contains carbon nanotubes. Furthermore, there is described a (confocal) optical imaging system having such a perforated disk.
