Tmt secondary mirror
WebbEight first- and second-generation instrumental capabilities were defined for the first decade of TMT operation, including a wide-field optical spectrograph, mid- and high-resolution infrared spectrographs, and a multiple-IFU spectrograph. Up to seven of these instruments will work with AO systems which provide either partial AO correction WebbImage credit: LCO. Reflecting telescopes have many advantages over refracting telescopes. Mirrors don't cause chromatic aberration and they are easier and cheaper to build large. They are also easier to mount because the back of the mirror can be used to attach to the mount. Reflecting telescopes have a few disadvantages as well.
