Customized EOC



The MINI-EOC (Electron Optical Culumn) is available for surface analysis and measurements as an electron beam source of a low acceleration SEM. We have been fabricated the special types of MINI-EOC as below.


MINI-GUN

SampleFstar sand without corting

MINI-GUN was installed in the analyzer of the atomic stereo-microscope. The total length of MINI-GUN is 46 mm, the outside diameter is ƒΣ 12 mm. The configuration is as follows.
The secondary electron image of star sand (Right image) was observed in our test chamber. When the accelerating voltage was 1.5 kV and WD = 70 mm, the probe diameter was less than 12 ƒΚm and the probe current was 3 nA.
* A power supply is necessary to operate MINI-EOC.
* We also sell SED (Secondary Electron Detectors) for detection as a SEM.
