Custom Vacuum Chamber Sherography System

Production Shearography /Thermography System for aircraft composites manufacturing.  LTI manufactures the LTI-9000 Vacuum Shearography System that includes the 5100 Shear Camera, Gantry, Part Fixture and Vacuum Test Chamber. Test parts are scanned a section at a time and images may be stitched together in one file.

The LTI-9000 Vacuum Test Chamber is manufactured in 8×8, 12×12 ft. cross sections in incremental lengths of 4 feet. Test chambers may be configured to meet your program requirements using modular end door, man-door, and plain sections. Chambers are manufactured complete with blower and control valves, electrical wiring harness, interior lighting and optional closed circuit video. 

LTI provides complete installation, certification and training.

LTI Advantage

Shearography Vacuum Test Chambers have unique design features optimized for mechanical stability, high cycle rate, low noise, industrial safety, and laser safety. They are typically designed in 4 foot segment lengths, width and height. This design may be changed due to the customer size requirements: The chamber is typically provided with one (1) End Door and, one (1) Side Man Door. Test chambers are designed for a maximum operating pressure differential of 0.3Bar (4.41 psi).

Custom Integrations

Shearography systems can be adapted to existing scanners where practical and cost effective.
