Two-stage TE-cooled InGaAs detectors for low-noise near-infrared measurements from 0.8 to 2.6 µm.
DInGaAs-TE series detectors use two-stage thermoelectrically cooled InGaAs photodiodes for the 0.8–2.6 µm range. The DInGaAs1700-TE and DInGaAs2600-TE share the same construction with a 3 mm diameter active area; the sensor is held at -40 °C with ±0.5 °C stability by the ZTC temperature controller.
Key Features
- Two models covering 800–1700 nm and 800–2600 nm
- Two-stage TE cooling to -40 °C, temperature stability ±0.5 °C
- Ø3 mm active area on both models
- Typical NEP of 3.2×10⁻¹⁵ (DInGaAs1700-TE) and 5.5×10⁻¹³ (DInGaAs2600-TE)
- Current output; the ZAMP I-V transimpedance amplifier is recommended before an oscilloscope, lock-in amplifier or the DCS103
- Can be read directly by the DCS300PA data acquisition system, which has built-in amplification
- In cooled mode, operation requires the ZTC temperature controller
Typical Applications
- Low-light near-infrared spectroscopy
- NIR photoluminescence measurements
- Transmission and absorption measurements from 0.8 to 2.6 µm
- Lock-in detection with scanning monochromators
