arrow12Silicon Apertures

No-membrane frames

Our Silicon Apertures feature the same TEM window grid-style chip size but lack any suspended membrane so that there is a freely accessible opening through the chip frame.


  • Background-free Imaging – Open apertures for free suspension of materials so that they can be imaged without intervening membranes
  • Plasma Cleanable – Silicon apertures can be vigorously plasma cleaned to remove organic contamination
  • Silicon Composition – Chip frames comprise P-type doped silicon
