Abstract: The light microscopic studies of the surface of threaded parts of the photographic lens of a camera after their manufactoring, their hand polish, and after their different ultrasonic treatments are performed. The ultrasonic treatment of lens parts is found as significantly more effective method compared to hand polishing.

The effectivity of the ultrasonic treatment at different application of the horn on the two lens components and the horn shape are also studied and discussed.
