Summary
[edit]DescriptionNIRSpec Calibration Assembly (CAA) (15515758528).jpg |
This device is part of the NIRSpec (Near Infrared Spectrograph), one of the instruments that will fly onboard the James Webb Space telescope from 2018. The Calibration Assembly aids accurate colour measurements by periodically testing the accuracy of the instrument, allowing for corrections in the data.
