Blade Section Viewer for checking edge profiles

A critical component in all jet engines is the turbine blade - spinning at up to 10,000 rpm. The precise geometery of these components is well controlled and requires a quick, effective method of inspection on a large volume of components.

Optical sectioning is a well accepted method of checking the edge profiles of workpieces such as turbine blades, large and small.

The Spectrum Metrology Blade Section Viewer incorporates two lasers, each illuminating one side of the blade edge. The blade is displayed as a magnified image on the PC screen and compared against a template.

This configuration gives clear profile images at a magnfication of x50 for fast visual and comparative inspection.  Blades are held to  rest in a Vee fixture and moved across the laser path by the operator. A live video image is shown on the PC screen with an optional template overlay.  Images can then be saved to file if required.


Field of View: approx 5mm x 6mm
Length of edge that can be checked as standard: 360mm
Magnification: x50

* Alternative configurations can be designed to meet individual requirements.
