Automated milling angle adjustment
Automated milling angle adjustment using the touch screen is an available option for the TEM Mill. Adding this capability enables you to create multi-step milling sequences that include the automatic adjustment of milling angles throughout the milling process.
A laser light source and a photodetector sense transmission of light through the specimen. A programmable sensitivity control automatically stops the ion milling process as the specimen becomes translucent.
Liquid nitrogen-cooled sample stage
Although milling at low angles with low ion beam energies reduces sample heating, temperature-sensitive samples may require further cooling. The SEM Mill’s liquid nitrogen system features a dewar located within the enclosure that is fully integrated and interlocked effectively eliminating heat-induced artifacts.
In situ sample viewing
The ion milling process can be monitored in situ in the milling position when using either the optional stereo or the high-magnification microscope. The stereo microscope (7 to 45 X) enhances sample viewing and with its long working distance allows the sample to be observed in situ while milling. The 1,960 X high magnification microscope coupled to a CMOS camera and video monitor to view samples and capture images in situ during milling. This system is ideal for preparing site-specific samples.
Vacuum or inert gas transfer capsule
An optional vacuum capsule allows you to transfer the sample to the SEM under vacuum or in an inert gas.
