OEM - Sensoren
For installation as energy monitors in lasers or for customer
specified solutions


These sensors are characterized by a high sensetivity a high repetition rate. Because of the windowless design and the used metallic absorption coating an usage also in the UV-range is possible. The sensors of the PEO 8A and PEO 12A type have a built-in preamplifier which improves the insensitivity to interference and avoids problems when using longer signal cables. If needed, for example when using the senor at different wavelengths, these sensors can be supplied with our reliable, broadband, absorbing black coating. Our modular construction set for energy monitoring is the ideal completion for these sensors.
