The form suggests a spectrum-related visual record, but the precise technical meaning remains specialized and only partly recoverable from the morphemes alone.

Etymology

Spectrograph can also mean the picture or record produced by that machine, and the name comes from spectrum ('a range of light or colors') plus graph ('a drawing or record'), like in photograph. So a spectrograph is the recorded image that shows the different lines or colors from a light source.
