A Constant-Time, Variable-Intensity Microsecond Exposure Sensitometer

Frank P. Herrnfeld

The constant-time, variable-intensity sensitometer was designed for investigating the response of photographic film in the microsecond exposure region. The fastest time available is 1.5 /μsec with 2 w/sec of energy per flash. Exposure times of 15 and 150 μsec at identical energy level per flash are also available.
