The FTIR utilized by ASPECT consist of a modified MR-254; high temporal resolution (75 Hz) system Dual input design with Signal port and Cold source reference port.
Two detectors are utilized including a 3 –5 and 8 – 12 micron providing coverage in the atmospheric IR window. Unit ready for operation in under 4 minutes after power-up. Chemical detection is automatic using a pattern recognition algorithm
