Detectors (UV-Visible-NIR Sensitivity) |
| |
 |
InGaAs PIN photodiodes (for 0.5-2.6 µm) |
This detector type typically has sensitivity within 0.5–2.6 µm. Various spectral response ranges, active areas, arrays, and packages are available. |
| |
 |
PbS photoconductive detectors (for 1-3.2 µm) |
PbS photoconductive detectors are sensitive to 1–3.2 µm wavelengths. PbSe photoconductive detectors are sensitive to 1.5–5.2 µm. |
