Abstract:
The invention provides an infrared upconversion spectrometer for determining a mid-IR spectrum of received infrared light with a high resolution. The spectrometer applies upconversion to transform light in the mid-IR to the near-IR range where efficient detectors are available. The up-conversion causes divergence of the light, and in addition, the invention applies an extra dispersive element to record a spectrum.
