Photos: NASA's Advanced Landsat Earth-Watching Satellite

Operational Land Imager (OLI) Telescope


The OLI telescope uses a four-mirror compact design. The optics are positioned inside a lightweight, yet highly stable, carbon composite optical bench (i.e., a substrate on which the optics are mounted) that has special features to control undesired stray light (stray light is any light entering the optics from someplace other than the observed Earth surface, or imaging “target”).
