Embodiment Construction
[0026] The present invention will be described in further detail below through examples, and the following examples are explanations of the present invention and the present invention is not limited to the following examples.
[0027] Such as figure 1 As shown, a large-field far-ultraviolet spectral imager of the present invention includes a Gregorian telescope, a monochromator, imaging optics and a detector. The monochromator separates the incident beam collected by the telescope into several wavelength channels (three in the figure) along the direction of dispersion. The channel bandwidth can be adjusted by the width of the incident and exit slits of the monochromator to adapt to different spectral resolutions. rate demand. Each separated channel is converged by an independent imaging mirror to form a full-field image, and the images of different channels are finally formed in different areas of the same MCP detector.
