  • Patent number: 10146102
    Abstract: The invention relates to an iris device (1) for optical imaging systems (71), comprising an aperture arrangement (5) and to a medical imaging system (72) comprising a sensor (15), in particular a camera (15a). Conventional iris devices (1) known from the art unavoidably suffer a necessary trade-off between the depth of field and the amount of light transmitted through the optical system (71), i.e. in particular the amount of light incident on the sensor (15). This disadvantage results from the fact that iris devices (Wo one) of the art transmit or reject light in the same way for all wavelengths (43), i.e. show a spectrally flat transmission property.
