Surface cleaning of CCD imagers using an electrostatic dissipative formulation of First Contact~(TM) polymer

摘要

We describe the results obtained cleaning the surface of DECam CCD detectors with a new electrostatic dissipative formulation of First Contact~(TM) polymer from Photonic Cleaning Technologies. We demonstrate that cleaning with this new product is possible without ESD damage to the sensors and without degradation of the antireflective coating used to optimize the optical performance of the detector. We show that First Contact~(TM) is more effective for cleaning a CCD than the commonly used acetone swab.
