Spitzer

instruments

• IRAC

测光，(3.6 µm, 4.5 µm, 5.8 µm and 8 µm)，在2009之后，还有最短的两个能用

8µm波段主要用于测量7.7µm的PAH辐射，WISE的12µm波段太宽了。（而且11.3µm的中性PAH辐射不trace SFR）

分辨率大概1.2arcsec

• MIPS

(Multiband Imaging Photometer for Spitzer), 远红外：24 µm, 70 µm, 160 µm

分辨率：6arcsec（24 µm）

• IRS

光谱仪器：four sub-modules which operate at the wavelengths 5.3–14 µm (low resolution), 10–19.5 µm (high resolution), 14–40 µm (low resolution), and 19–37 µm (high resolution).
