Development of focal plane systems, detector arrays, and electronics
Development of focal plane systems, detector arrays, and electronics

Personnel in the DCL can help develop detector systems from the design phase through the entire new product development lifecycle.

Detector Fabrication

Goddard’s Detector Systems Branch also includes the Detector Development Laboratory (link opens new browser window). This MEMS and nanotechnology fabrication facility can be used by U.S. companies, universities, and other government agencies for prototyping and developing semiconductor devices such as focal plane arrays and other radiation detectors.
