What do you do when you need to let air and water circulate but can’t let light get out? That’s the challenge we faced in adding a fluorescence excitation filter to a custom diver propulsion vehicle. You can’t allow air to be trapped behind the filter or it will break as the diver descends and a pressure differential builds up on opposite sides of the glass. The answer was to make a custom 3D-printed filter holder that allowed easy air and water flow while not providing a direct path for light. Read the full article.
