| titleOfInvention | An Athermalized Mid-Wave Infrared Spectrometer |
| abstract | The invention provides an adiabatic mid-wave infrared spectrometer, which solves the problem that the conventional mid-infrared optical system cannot obtain the same imaging quality at room temperature and low temperature. The invention includes a low-temperature box, a mid-wave infrared window and a spectral imaging system; the mid-wave infrared window is arranged on the lower side wall of the low-temperature box; the spectral imaging system is arranged in the cavity of the low-temperature box; the spectral imaging system includes a slit and a reflector , a lens assembly and a photosensitive surface of a detector; the lens assembly includes a first lens, a second lens, a third lens, a fourth lens, an aperture stop, and a dispersion element arranged in sequence on the same optical axis; the light beam is incident from the mid-wave infrared window to After the slit, it is reflected by the mirror and enters the lens assembly. The light beam is incident on the dispersion element in the lens assembly, dispersed and reflected back to the lens assembly, and finally enters the photosensitive surface of the detector. The invention realizes that the infrared optical system has the same imaging quality at normal temperature and at low temperature. |
