An imaging device can include: an imaging module a lens associated with the imaging module and an optically transmissive inflatable member surrounding the lens. The inflation tube can be fluidly coupled with the inflatable member. An inflation port can be fluidly coupling the inflation tube and inflatable member. A fastener that fastens the inflatable member can be coupled to a housing of the imaging module. A flushing tube can be fluidly coupled to a flushing port that is directed outward from a housing of the imaging module. The inflation tube and/or flushing tube are coupled to a pneumatic system that can pump fluid therethrough. The inflatable member can be an inflatable membrane, balloon, bladder, or bag.
