Definition

A Multi-Mirror Telescope (MMT) employs multiple mirrors to collect and focus light, instead of a single large mirror. This design improves resolution and reduces construction costs compared to traditional telescopes with single large mirrors.

5 Must Know Facts For Your Next Test

  1. The original MMT used six individual 1.8-meter mirrors working together as a single optical system.
  2. Multi-mirror designs can be reconfigured or upgraded more easily than single-mirror telescopes.
  3. MMTs reduce the weight and structural challenges associated with large single-mirror telescopes.
  4. Adaptive optics are often used in conjunction with MMTs to correct for atmospheric distortion.
  5. The MMT Observatory, located at Mount Hopkins in Arizona, was one of the first major implementations of this technology.
