An astronomical instrument is a device for observing, measuring or recording astronomical data. They are used in the scientific field of astronomy , a natural science that studies celestial objects and the phenomena that occur in the cosmos, with the object of explaining their origin and evolution over time.

Star Diagonal: Used to change the angle of the light coming out of a telescope, for easier viewing. Herschel Wedge: Similar to a star diagonal with a wedge-shaped unsilvered prism reflector that reduces incoming light by up to 95% for solar viewing. Coma corrector a correcting lens used to reduce coma distortion in fast reflecting telescopes.
The oldest form of astronomy, optical or visible-light astronomy, observes wavelengths of light from approximately 400 to 700 nm. [149] Positioning an optical telescope in space eliminates the distortions and limitations that hamper that ground-based optical telescopes (see Astronomical seeing), providing higher resolution images.

Whereas most of the other instruments on Webb can see from the start of near infrared, or even as short as orange visible light, MIRI can see longer wavelength light. [1] MIRI uses silicon arrays doped with arsenic to make observations at these wavelengths. [1] The imager is designed for wide views but the spectrograph has a smaller view. [1]
