Overcoming battery challenges in test & instrumentation equipment

摘要

An investigation into how this occurred pointed to a reflective null corrector, which is a device used to test and properly shape non-spherical mirrors. This device had been assembled specifically for the telescope's construction, but had been done so incorrectly, with a lens 1.3mm out of position. This slight difference had a significant impact on the usefulness of the telescope, until it was able to be balanced out, three years later. This led to a series of expensive launches to fit and replace instrumentation over the subsequent years. Although most instrumentation applications tend to be closer to home, the Hubble Space Telescope highlights how even slight deviations in measurement can have significant consequences. Design engineers working on test, measurement and instrumentation devices aim to guarantee precision by specifying high quality components and ensuring designs are fit for purpose and functional. One of these components is the power source.
