Saunders/Durst LPL Lens Board Threading
|Saunders/Durst LPL lens boards require a minor modification to the mounting hole to allow the installation of a 150mm Apo Componon. Rather than using a mounting flange or retaining ring, the lens board was rethreaded.
Depending on the lens board design/material, threads can often be cut into a lens board. This option reduces the number of components required for a mounting, the weight of the overall system, and can be a more cost effective solution that purchasing a replacement retaining ring or flange.
