1. A camera assembly comprising:
a housing having an opening configured to receive a combined light, which enters the housing along a combined light path, the combined light including visible light and infrared fluorescence light;
an aperture mechanism having an adjustable opening disposed along the combined light path, wherein the aperture mechanism is adjustable at least between a first configuration in which the adjustable opening has a first size and a second configuration in which the adjustable opening has a second size that is smaller than the first size;
a visible light sensor configured to receive the visible light and to generate visible light image data;
an infrared sensor configured to receive the infrared fluorescence light and to generate infrared fluorescence image data; and
a controller configured to:
adjust the aperture mechanism at least between the first configuration and the second configuration;
operate the camera assembly in an observation mode during which the aperture mechanism is in the first configuration and a navigation mode during which the aperture mechanism is in the second configuration, wherein the controller activates a near infrared light source while the camera assembly is operable in the observation mode and deactivates the near infrared light source while the camera assembly is operable in the navigation mode.
