Swing Prism borescopes from Hawkeye

HAWKEYE SWING PRISM BORESCOPE OFFERS UNIQUE VERSATILITY WITH A VARIABLE DOV OF 16º - 118º

Hawkeye Blue Swing Prism borescopes have a tiny prism at the tip that pivots, or “swings,” to vary the direction-of-view from 16° to 118°. A ring on the borescope body controls the prism direction. The field-of-view is 45°, so the borescope effectively sees from -7° to 133°. Another ring focuses the borescope, and a third rotates the borescope tube over more than 360°, side-ways in any direction, without turning the body.
