Maximum current
Describes the size of a load that can be driven by an instrument with a Loop Impedance
mA output. For example a 500 ohm maximum loop impedance means that the instrument can supply 10 volts at 20 mA into this load.
MCT (Mercury Cadmium Telluride) or HgCdTe
A ternary alloy material used to build photon detectors that are sensitive in the 3-5 µm
and 8-14 µm regions of the spectrum and require TE cooling in the 3-5 µm region and
cryogenic cooling in the 8-14 µm region.
Minimum spot size
The diameter of the smallest object for which an instrument can meet its performance
specifications.
