Model-by-model comparison
The full manufacturer-published comparison is transcribed below so model differences remain visible rather than being reduced to a single range.
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.

| NEP, typical | 3.2 × 10⁻¹⁵ | 5.5 × 10⁻¹³ |
| Operating temperature | −40 °C | −40 °C |
| Temperature stability | ±0.5 °C | ±0.5 °C |
| Ambient temperature | +10 to +40 °C | +10 to +40 °C |
| Signal output | Current | Current |
| Output polarity | P | P |
| Temperature controller | ZTC | ZTC |
Design and integration details
- 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.
Application and connection notes
- 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.
