- EIT
-
- With a telescope focal length of 1.652 m and a pixel size of 21 micrometer, the plate scale of the EIT images is 2.6 arc
- sec per pixel. The optics are divided into quadrants of matched multilayer pairs that are tuned to bandpasses selected
- for observation of the chromosphere and corona at all phases of the solar cycle. The quadrants are isolated by a rotating
- mask that permits only one bandpass to view the Sun at a time.
