The Miniature Angle-Beam or ROMPAS Calibration Block 

The miniature angle-beam is a calibration block that was designed for the US Air Force for use in the field for instrument calibration. The block is much smaller and lighter than the IIW block but performs many of the same functions. The miniature angle-beam block can be used to check the beam angle and exit point of the transducer.

The block can also be used to make metal-distance and sensitivity calibrations for both angle and normal-beam inspection setups. Contains a 1.0″ radius opposite a 2.0″ radius, and a 5/64″ diameter x .750″ deep flat-bottom hole.

• DIMENSIONS: 1.000″ THICK. (ALSO AVAILABLE IN .500″ THICKNESS, SEE HERE)
• IN ACCORDANCE WITH ASTM E164 AND U.S. BUREAU OF PUBLIC ROADS, TYPE B SPECIFICATIONS.
