Vergelijking per model
De volledige vergelijking van de fabrikant staat hieronder, zodat modelverschillen zichtbaar blijven en niet tot één bereik worden teruggebracht.
Two responsivity/detectivity exponents are poorly encoded in the manufacturer HTML and are therefore marked for confirmation rather than silently corrected.

Ontwerp- en integratiedetails
- Room-temperature photoconductive PbS detectors with an integrated preamplifier.
- Voltage output and selectable ×1, ×10 and ×100 gain.
- Intended for lock-in detection over the 0.8–3.2 µm region.
Toepassings- en aansluitnotities
- Use a lock-in amplifier; select voltage-input mode when pairing with DCS103 or DCS300PA.
- The source recommends 400 Hz modulation within the 100–1000 Hz response range.
