Tip Preparation Sub-Facility
Transmission Optical Microscope
and Integrated Micromanipulator
Instrument Model: 4290-3DM
Manufacturer: Custom Probes Unlimited
Transmission optical microscopy is ideal for monitoring the etching of
metal wires into controlled geometry tips. Designed by Dr. Allan Melmed,
the CPU System 4290-3DM from Custom Probes Unlimited will help develop a standardized
procedure for fabricating tips for filed ion microscopy (FIM) and three-dimensional
atom probe microscopy (3DAP).
This system consists of a 3-D pneumatic micromanipulator and a specially
equipped microscope equipped with some accessories:
3-D joystick controlled pneumatic micromanipulator
3-lens optical microscope adapted for 210mm barrel length with X-Y
adjustable stage and specimen clamp
1.25na substage condenser
Tungsten lamp illuminator
15x wide view eyepiece
5x and 10x conventional objective lens
Nikon 50x long-working distance objective lens (13.8mm), 0.45na
Protective glass slides for lenses
Wire loops for micropolishing W-like and Pt-like metals
Instructions for Pt/Ir etching are now available
