7. EANING Both the optical window and the CCD cleaning are carried out in the clean room by means of a 30 magnifying power microscope This procedure removes any dust which can otherwise bring about unmistakable marks on the image you have taken In particular such spots increase as the focal ratio gets wider In other words an image may not show any mark at f 5 6 but it can be clearly noted at f 32 because of an obvious geometrical problem of projection Due to the shutter or elapsed time the external surface of the optical window may gather dirty particles that may be easily removed To perform such task we use a compressed air cylinder specifically designed for optical cleaning Be careful There are similar products that instead of using compressed air use a liquefiable gas at ambient pressure it quickl assifies thus triggering an air compressed effect You do not absolutely have to use these products they may give rise to heavy marks or rings on the windows itself A product we can recommend is DUST OFF provided by EDMUND OPTICS Thanks to DUST OFF or any other similar product it is very easy to get rid of any microparticles keep the shutter open for a few seconds by the camera control program and spray some air blast We kindly advise you against using cloths optical paper and cleaning liquids because the dirt will be only mixed up or even worse increased The risk is to finally damage the coating of
