Offered here is a genuine U.S. Army M1 Infinity Aiming Collimator, a precision optical instrument historically used for aligning artillery fire control systems. This unit is in good condition, though it is surplus and may be missing ancillary components such as straps or locking clips. It remains an excellent example of Cold War-era U.S. Army field artillery technology and is ideal for collectors, restoration projects, and museum displays.
Historical Context
The M1 Infinity Aiming Collimator was a critical component in U.S. Army artillery calibration kits from the World War II era through the Cold War. It was used to project a fixed optical point—typically a crosshair—to simulate a target at an infinite distance, allowing artillery crews to align fire control instruments such as the M2 or M2A2 aiming circles without relying on terrain-based landmarks.
This device played a crucial role in the preparation of indirect fire missions, particularly under conditions where visibility or topography made traditional optical alignment difficult. The M1 Collimator ensured greater accuracy in establishing azimuth references and aligning artillery batteries, from 105mm and 155mm howitzers to larger-caliber field pieces.
