An apparatus and method for producing a substantially uniform bond line thickness by utilizing a crosshatch, grid pattern, or spacers of like patterns in a receptacle of a transducer housing. Certain embodiments include a housing configured to retain a transducer. The housing includes an annular wall and a receptacle adjacent to the wall. The receptacle has a member configured to allow radiation to pass through it. The member has a first surface and a second surface. The spacers on the first surface are configured in a grid pattern to maintain uniform spacing and a uniform bond line thickness between the transducer and the member. The bond line is further controlled by the depth of the spacers, which are configured to maintain a generally constant bond line thickness.
