1. Germanium (Ge):
- The maximum spectral response of germanium is around 1.8 micrometers (µm). This means that germanium detectors are sensitive to infrared radiation with wavelengths up to 1.8 µm. Beyond this wavelength, the response of the detector decreases rapidly.
2. Silicon (Si):
- The maximum spectral response of silicon occurs at approximately 1.1 micrometers (µm). Silicon detectors are therefore primarily suited for detecting infrared radiation in the near-infrared (NIR) region of the electromagnetic spectrum, up to wavelengths of around 1.1 µm.
It's important to note that these values are approximate and can vary slightly depending on the specific properties and characteristics of the germanium and silicon detectors.
