3.4.2 Water Connection Overview
In order to best achieve the minimum flow rates, it is recommended to make all water-cooling
connections in-series. The following sequence outlines the typical water cooling connection to the head.
1. Water inlet to the fiber
2. Water outlet from the fiber
3. Water inlet to the collimator
4. Water outlet from the collimator
5. Water inlet to the scanner body
6. Water outlet from the scanner body and return to the laser or chiller
Figure 3-1 outlines a typical in-series water connection to the scanner. Although a 2D High-Power
scanner is pictured, the same principle applies to the Mid-Power scanner (Water Cooling Supply  Fiber
 Collimator  Water Cooling Return). Please note that water flow is not limited to a specific direction
through the fiber, collimator, or scanner body.
