Infrared Associates FTIR-M16-1.00 Detector

The Infrared Associates FTIR-M16-1.00 is a mercury cadmium telluride (MCT) detector designed for Fourier Transform Infrared (FTIR) spectroscopy applications. Here’s a breakdown of its key features and specifications:

Key Specifications:

1. Detector Type: Photovoltaic MCT (HgCdTe)

   • Optimized for fast, high-sensitivity mid-infrared detection.

2. Active Area: 1.0 mm diameter (common for FTIR applications).

   • Suitable for high-throughput spectroscopy systems.

3. Spectral Range:

   • Typically covers ~2 µm to ~16 µm (5000 cm⁻¹ to ~625 cm⁻¹), depending on the HgCdTe alloy composition.

   • May require cooling for optimal performance in the longer wavelength range.

4. Cooling Requirement:

   • Likely requires liquid nitrogen (LN₂) cooling or thermoelectric (TE) cooling to reduce dark current and improve sensitivity.

   • Some MCT detectors operate at 77 K (LN₂) for best performance.

5. D (Specific Detectivity):*

   • High D* (typically >10¹⁰ Jones at peak wavelength), making it sensitive for low-light FTIR applications.

6. Response Time:

   • Fast response (likely in the microsecond range), suitable for rapid-scan FTIR systems.

7. Application:

   • Used in FTIR spectrometers, gas analysis, industrial process monitoring, and research applications requiring high-speed IR detection.

Typical Use Cases:

• FTIR Spectroscopy (especially rapid-scan systems).

• Emissions Monitoring (e.g., environmental gas analysis).

• Chemical Imaging & Hyperspectral Systems.

• Research & Industrial QA/QC.
