The method that is not utilized for checking the visual clarity of a rigid endoscope is employing a leak tester. A leak tester is specifically designed to assess the integrity of the endoscope's casing to ensure that there are no leaks that could compromise sterilization or functionality. This process focuses more on detecting structural issues rather than inspecting the clarity of the internal optical surfaces.

In contrast, other methods such as using a flashlight can help illuminate the interior of the endoscope, making it easier to identify any debris or obstructions that may affect visual clarity. Visual inspection with the naked eye allows for a straightforward assessment of cleanliness and clarity. Additionally, using clear water as a testing medium can highlight imperfections or residual materials since the clarity of the water will reveal any cloudiness caused by contaminants. Each of these methods directly pertains to evaluating the visual clarity of the endoscope, while a leak tester serves a different purpose altogether.
