NH-3NZ “Nozzle inner diameter / depth measuring instrument”

High precision automatic measurement of nozzle diameters and depths without destruction!

NH-3NZ with the point autofocus probe and the image processing offer fast and high precision automatic measurement of diameters / depths of small diameter nozzles such as inkjets, synthetic fiber spinnerets, fuel injection nozzles, etc.

Features

Non-destructive measurements of diameters and depths of small diameter nozzles.
Fast / high precision measurements by the point autofocus probe and image processing function.
The automatic XY stage offers fully-automatic measurements of multiple holes.

Specification

Movable range: (X, Y, Z (AF)) = 100 x 100 x 10 mm
Scale resolution: (X, Y, Z (AF)) = 0.1μm, 0.1μm, 0.01μm
Nozzle measuring range: approximately φ10μm - 1mm
Hole depth: Z = 10μm - several mm

Nozzle edge detection (image processing AF function)

ノズル断面図

The nozzle edge detection is capable of detecting a nozzle edge by moving the objective to a position where a curve can be observed and analyzing the image near the nozzle edge (in Z axis direction) (The image processing AF function)

The image processing autofocus function offers non-destructive measurement of a nozzle edge by detecting a ring which was generated by the scattering light of the transmissive illumination.
