Paper Abstract

Although the interest in PtSi infrared focal plane array (IRFPA) has waned due to its low quantum efficiency compared with InSb and HgCdTe arrays, it is very potential in observing brighter celestial objects. We explored the possibility of applying it to the observation of infrared solar spectrum. In the paper, the methods of the simulation and calibration in our observation are introduced and discussed in detail. Using this kind of camera, a new observational band (FeI 1.56 micrometers ) is added to the Two- Dimensional Multi-Band Solar Spectrograph at Yunnan Observatory. The dispersion for FeI 1.56 micrometers of the new infrared solar spectrograph is 0.0722 angstrom per pixel, and each vertical pixel represents 0.51 inch of solar disk. It is specially suitable for 2D spectroscopic observation of the deepest solar photosphere. Some primary observation results are also presented.
