In the following, the functional characteristics of the correction astigmatism for astigmatism spectrometer in the various embodiments described above is better described, with reference to
Fig. 4 a-4c and Fig. 5 a-5c are further elaborated it：
Fig. 4 a-4c are respectively the schematic diagram of detector plane focal beam spot astigmatism in the embodiment of the present invention；Wherein, Fig. 4 a are

Figure, Fig. 5 c tilt cylindrical lens astigmatism spectrometer in detector plane focal beam spot root mean square radii with wavelength variation relation
Figure.
Since symmetrical and staggered form Cheney that-Tener structure its focal plane of spectrometer is there are astigmatism, and astigmatism is big
It is small to change with the variation of wavelength.By in comparison diagram 4a, Fig. 4 b and Fig. 4 c, each detector plane focal beam spot astigmatism it is big
It is small, it can be clearly seen that by increasing cylindrical lens in original light path and tilting, astigmatism can be eliminated well, comparison is as follows：
1) non-imaged spectrometer
Fig. 4 a show a kind of schematic diagram of astigmatism increased image planes disperse hot spot with the increase of wavelength.Shown in Fig. 5 a
It is a kind of to design detector plane focal beam spot root mean square radii in example, with the variation relation figure of wavelength, which can characterize at this time

This characteristic that can be converged and dissipated to light beam in one direction using cylindrical lens corrects astigmatism.But by
Picture different in the size of the astigmatism on each wavelength, that the cylindrical lens face of similary curvature is corrected in the case of same distance
Scattered amount is basically identical, and the calibration result of astigmatism also has relationship with the space incident angle of incident ray, therefore parallel with focal plane
Cylindrical lens can only be directed to a certain wavelength calibration astigmatism, other wavelength location correcting values are limited.Such as：As shown in Figure 4 b, it is
To the schematic diagram of disperse hot spot of each wavelength after centre wavelength astigmatism in image planes；As shown in Figure 5 b, it is a kind of design example
After middle addition cylindrical lens are to astigmatism at centre wavelength 0.925um, detector plane focal beam spot root mean square radii is with wavelength
Variation relation figure, the astigmatic correction of centre wavelength is to preferable level at this time, and both ends spot size still has 30~40 μm.
3) cylindrical lens astigmatism spectrometer is tilted
In order to weigh the astigmatism of each wavelength, by micro inclination cylindrical lens, while adjust cylindrical lens curvature and column it is saturating
Mirror and the distance of focal plane, you can realize different wave length light reached after cylindrical lens focal plane light path it is different, so as to
The aberration correction quantity of each wavelength is different, and the astigmatism of each wave band is compensated with this.
Fig. 4 c show the schematic diagram by tilting disperse hot spot of each wavelength in image planes after cylindrical lens astigmatism, each wave
Long astigmatism can reach smaller level；Fig. 5 c, which show to add in a kind of design example, tilts cylindrical lens to complete wavelength range
After interior progress astigmatism isostatic correction, detector plane focal beam spot root mean square radii is with the variation relation figure of wavelength, at this time each wave
Long astigmatic correction is to preferable horizontal.
Compared with existing spectrometer, the various embodiments described above of the present invention have the following advantages：
In the embodiment of the present invention, by adding in cylindrical lens in original grating spectrograph system, it can substantially reduce light
Spectrometer designs the astigmatism in wavelength band at it.Wherein, cylindrical lens can parallel focal plains setting, for the astigmatism on each wavelength
Size is different, and the amount of astigmatism that the cylindrical lens face of similary curvature is corrected in the case of same distance is basically identical, and
The calibration result of astigmatism also has relationship with the space incident angle of incident ray, therefore the cylindrical lens parallel with focal plane can only be directed to certain
One wavelength calibration astigmatism, other wavelength location correcting values are limited.
In addition, it can further be promoted by adding in the cylindrical lens for having certain angle in original grating spectrograph system
The calibration result of astigmatism.According to the size of actual spectrum instrument astigmatism and its variation relation with wavelength, the curvature of cylindrical lens is designed
And angle of inclination, it can greatly reduce spectrometer and design the astigmatism in wavelength band at it, so as to obtain energy on focal plane
The higher focal beam spot of quantity set moderate, and the sink-efficiency of each wave band luminous energy is reached unanimity, the collection of spectrometer can be improved
Efficiency improves the uniformity of the sensitivity of instrument and the response of each wave band.
The foregoing is merely the embodiment of the present invention, are not intended to limit the invention, it is all the present invention spirit and
Within principle, any modification, equivalent replacement, improvement and so on should all be included in the protection scope of the present invention.
