What materials are used in the water cooling modules of the Power Meters?
The standard water cooling modules are made of Aluminum. This material has an excellent heat transfer coefficient, allowing our water cooled detectors to go to high powers, even with small apertures. You can also have a Stainless Steel cooling module. This is the material of choice when working with deionised water in purified environments. Be careful though, the heat transfer coefficient of Stainless Steel been slightly lower, you will have to use a stronger water flow to get as high in power as with an Aluminum detector.
