Originally
designed for use with ASM and GCA (Integrated Solutions) Wafer Steppers,
the Model 357 Exposure Analyzer is a microprocessor based instrument
that performs measurement, storage, and recall of nine series of readings.
It reads intensity, energy, and time (1600 mW/cm2, 4000 mJ/cm2, 2.5
seconds max). For 365 and 436 nm wavelengths. Other wavelengths are
available.
