Description
Very Close Spacing Probe (0.5mm spacing)
Jandel Engineering Limited manufactures the very close spacing probe (0.5mm spacing) for measurements made very close to the edge of samples or for measurement of very small samples. The image above shows a comparison between the 0.500mm spacing probe and a ‘standard. 1.591mm spacing probe. All Jandel probes are built to a high level of mechanical accuracy. Specifications for radii, spacing and planarity are verified by video inspection system and optical interferometer. Loads are verified by electronic force gauge. Each probe has upper and lower jeweled needle guides.
