The standard JEOL room temperature holder is wide and has a limited tilt range (±20°) in our JEOL JEM 3200FS and ±XX° in the JEOL JEM 1400plus. On the other hand, it is very stable and produces high resolution images over this entire tilt range. Resolution tests were conducted using a holey carbon film that had both graphite fragments and "islands" of (poly)crystalline gold (the so-called "combined test specimen").
The images below were recorded using a microscope magnification of 300,000x (~377,000x at the CCD) and an exposure time of 1 second. We also offer higher magnification images of the gold on another page.
