Fine Pitch Positioner


Fine Pitch Positioner<FPP03-13>

Model Number Price Quantity RFQ
FPP03-13 is a drive mechanism developed for alignment equipment used for optical device assembly where high resolution is required. This drive can smoothly follow alignment operations within ±0.1 dB. Kohzu's exclusive design allows submicron-level positioning that is difficult to achieve with other micrometers. Also backlash is prevented when the holder is mounted on one of our stages.



●This mechanism allows submicron-level positioning that is essential for fiber alignment.
●High sensitivity makes sub-micron level positioning possible.
●Eliminates backlash (when used with Kohzu stages).
