Optical filter mount

All Filter-Mount products are manufactured in a certified cleanroom of class 7. JOMESA Filter Mounts FR60x60 for cleanliness analysis, permanent storage of filters. JOMESA filter mounts consist of a plastic backside and glass cover on the frontside. The backside can be used for information. Filter membranes vary in thickness and must be underlayed by a paper to prevent slipping. This paper underlay is helpful also for centering the filter. The glass frames are washed in an industrial washing machine, and dried in a HEPA filtered air flow. After washing and drying the Filter-Mounts are assembled in a class 7 cleanroom. JOMESA Slide-Mounts have 2 glass frames. The glass frames are washed in an industrial washing machine, and dried in a HEPA filtered air flow. After washing and drying the slide-mounts are assembled in a class 7 cleanroom. The slide-mounts are packed in a double PE cover. To ensure cleanroom handling, one lifts the inner PE packing outside the cleanroom and transports the inner packing into the cleanroom. Thus contamination by transport and carton packing does not enter a cleanroom. JOMESA SEM Filter-Mounts SEM60x60 Measuring (nonconducting) filtermembranes in a SEM leads to charging of particles. Due to charging particles may jump away during measurement. JOMESA developed a patented method (US 11,318,727 B2 and DE 10 2018 121 948 B4) for fixating particles in SEM analysis. SEM filter mounts consist of a bottom glass pane (onto which the filter is placed) with 2 markers. The markers are visible in an optical as well as in a SEM microscope .
