Ontwerp- en integratiedetails
- Large 100 mm² active area in UV-enhanced and blue-enhanced versions.
- BNC current output and direct mounting flange for Omni-λ monochromator slit assemblies.
- ZAMP transimpedance amplifier recommended when voltage output or improved sensitivity is required.
- Direct current-input connection is possible when the downstream instrument supports it.
Toepassings- en aansluitnotities
- Use a ZAMP preamplifier with oscilloscopes, lock-in amplifiers or DCS103 acquisition when current-to-voltage conversion is needed.
- DCS300PA already integrates a signal amplifier, so an additional preamplifier is not required.
