STAUFEN IM BREISGAU, Germany, June 18, 2015 — Updated optical table columns and pins from Owis GmbH can be secured additionally with a clamping fork. Mounting is independent from the thread grids and is possible in any desired position. For clamping the STF 15 pins, the SL 12/16 columns are equipped with plastic screws. Thus, the pins are fixed securely in the beam without sustaining damage. The columns can also be attached with M6 internal and external screw threads. The pins are also available with M4 and M6 external threads. The appropriate setscrews for M6 and M4 threads to each single STF 15 are included by default. The columns and pins are available in four lengths each, enabling setups with large differences in height or extremely low beam heights.
