Alessi Compact Probe Head

Jandel Engineering Limited manufactures the Compact Probe for use on Veeco FPP50000 and FPP100 equipment. It is also suitable for use on GRQ equipment or to replace square bodied probe heads manufactured by Alessi.
Some Veeco equipment requires a differently shaped probe (cartridge with lead). Please let us know if you are unsure which probe you require.

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.
