Improved Thermal Stability
Air currents can have a significant impact on thermal stability, particularly with large cold plates like the 260 Series LaserMount. For applications that need a very stable response, the 260-C is a custom-designed cover that fits snugly on top of the fixture and can be bolted down to prevent removal.
Nitrogen Purge Fitting
The 260-C also includes a 1/8″ barbed nitrogen purge nipple to purge the cavity to prevent condensation when operating below the dew point.
