ECAM-WFOV is one of the three standard lens options are available for the ECAM series visibleband cameras, providing wide field of view. ECAM standard lens options have no moving parts, are athermalized to provide stable performance over a wide range of temperatures, and are built to withstand the hazards of launch and long-term operation in orbit. For missions with highly-tailored instrument requirements, MSSS provides custom optical design and manufacturing services. MSSS develops custom optics with fields-of-view from 15 to 180 degrees using standard refractive optics, with longer focal lengths supported using catadioptric and reflective telescopic optics. Additional capabilities for custom optical systems include motorized focus adjustment and zoom lenses.
