U.S. M-1950 3H Lensatic Compass
The M-1950 U.S. military lensatic field compass with self-luminous lighting (designated the Model 3H by Cammenga) is fitted with self-luminous tritium vial lighting. Under U.S. military specification (MIL-SPEC) performance criteria, ten pre-production samples of the M-1950 are required to meet a battery of performance, durability, and accuracy standards.[1] This includes an overall inherent accuracy standard of ±40 mils (2.25 degrees) from actual magnetic azimuth;[1][2] a tritium illumination test;[3] and a shock or impact test, in which samples of the M-1950 are tested dropping the compass from a height of 90 cm (35 in.) on a solid surface covered with 10 cm (4 in.) of plastic-covered sand,[4] followed by testing to ensure performance within specified accuracy standards.[1][5] A water leakage test is also performed.[1][6]
