Segmented Mirror

(a telescope mirror formed of array of smaller mirrors)

A Segmented Mirror is a Reflector Telescope mirror formed by aligning smaller mirrors (Optical Segmentation). Keck Observatory was a pioneer. Alignment must be maintained to a high degree of precision and Adaptive Alignment is typically performed under computer control. Example telescopes with segmented mirrors:

Non-segmented (Monolithic Mirror) examples:
