Overview
Advantages
- Available in standard refracted angles of 0°, 45°, 55°, and 60° in steel for angle-beam inspections from 30° to 70°, SW or LW
- Stainless steel screw receptacles provide a firm anchoring of probes to wedges.
- Lateral electronic scanning replaces the hand-skewing movement (with lateral wedges).
- The IHC wedge option can be ordered to improve the quality of the inspection: irrigation, mounting holes for the wedge holder to work with any Olympus scanner, and carbide pins to increase wear resistance.
- Wedges are designed to perform manual or automated scans.
- Custom wedges with specific refracted angles can be ordered; wedge shape and contour can also be customized.

Wedge Offset Parameters
How to Find the Wedge Parameters
- Find the appropriate wedge in either the OmniScan or TomoView Wedge Database. Parameters are automatically set once the wedge model is chosen.
- If the wedge is not already in the database, you may download the latest database update from the Service & Support section of www.olympus-ims.com.
- Enter the parameters manually using the values provided on the Wedge Specification Sheet accompanying the wedge.
- Call your local sales representative.
