Vergelijking per model
De volledige vergelijking van de fabrikant staat hieronder, zodat modelverschillen zichtbaar blijven en niet tot één bereik worden teruggebracht.
The manufacturer parent-card title says DInAs, while the product body, response curve, hardware label and specification table consistently identify TE-cooled InGaAs models. The detailed model designation is used here.

Ontwerp- en integratiedetails
- Two-stage TE-cooled InGaAs detectors covering 0.8–2.6 µm.
- Both variants use the same detector-head construction.
- ZTC temperature controller is required for cooled operation.
- ZAMP transimpedance amplifier is recommended for current-to-voltage conversion and improved sensitivity.
Toepassings- en aansluitnotities
- The detailed source content identifies these models as DInGaAs1700-TE and DInGaAs2600-TE; the parent category card incorrectly labels the family DInAs.
- DCS300PA integrates a signal amplifier; an extra preamplifier is generally unnecessary with that acquisition system.
