FAQ

How can I download a software?

Simply go to the “software and firmware” menu in the Downloads section and choose your software in the list. Individual downloads for each product can also be found on the "Downloads" tab of each product page. In both cases, be careful in differentiating the monitor software from the PC interface software.

What is the minimum Power and/or Energy I can measure with my detector?

This value depends on the precision you want to have in your measurement. Usually, you take the noise equivalent value (NEE or NEP) and divide it by the percentage of precision you need. For example, if a precision of 5% is sufficient, you divide the NEE or NEP by 0.05. For a 1 mW NEP detector, this gives a minimum measurable power of 20 mW with a 5% precision. Be careful, this means that it is still possible to measure lower values, but that the noise portion will simply become bigger the closer you get to the threshold value.

How do I use Gentec-EO’s modularity concept to my advantage? (Can I change the cooling module?)

Gentec-EO’s modularity concept makes the detectors easy to choose within a family. By simply changing the cooling module, you can take the same detector from 15 W (standalone) to 200 W (with water cooling). This also means that you can change your cooling module if your requirements change overtime. Simply contact us for details.

Can I use my UP Power Meter post with my QE Energy Meter?

No. The posts for QE Laser Energy Meters are made of Delrin, a resin that is used as a substitute to metal and that is a natural insulator. This insulating property is necessary to isolate the highly sensitive energy detectors from the electromagnetic interference coming from the optical table. If used with QE Energy Meters, the steel posts of the UP Power Meters could raise the noise equivalent energy by a factor 10 or more.

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 deionized 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.
