A scope includes an elongate body, a lens at the distal end of the elongate body, at least one conduit, and a view optimizing assembly. The conduit is configured to connect to an air supply. The view optimizing assembly extends from the distal end of the elongate body past the lens and includes a first lumen and a second lumen, a plurality of dividers separating the lumens, and a deflector. The first and second lumens are in fluid communication with the conduit and are sized such that a single velocity flow from the conduit separates into a first flow through the first lumen and a second flow through the second lumen. The first flow has a higher velocity than the second flow. The deflector assembly is configured such that air exiting the first and second lumens combines to keep debris off of the lens.
