The LASPEC (Laze – spec) Software was developed specifically for the IR-3216, IR-6416, and IR-0144 systems. The software is written in Labview 7 and all of the source files, with exe and installer are provided.
The main screen presents the data gathered from the detector array, with the external input values listed to the right of the main graph.
All of the values presented are scaled to 10 Volt levels.
The software allows the user to change the integration parameters, such as Integration Gate Delay Time, and Integration Gate Width Time. Having the integration gate just slightly wider than the signal pulse will provide the best signal to noise.
The Scan Mode selector above the main graph selects the type of scan acquired: Background, Reference, Sample, Sample/Reference, Chopped and Zero External Inputs. The background is the residual level of the inputs without any laser power applied to the detector. Reference is the full laser power applied without any sample (100% scan). And the sample scan is the difference between background and sample, and the Sample/Reference is the sample data divided by the reference data, where a value of 1 indicates maximum. Zero External Channels allows the residual DC level to be subtracted from the External inputs.
Chopped Mode is for using a chopper in the optical path to alternately acquire reference and signal data points. External Input #16 is used for connecting the output of the chopper sync signal to the system. The software will monitor the level at External Input #16 and use this information to determine the phase of the data acquisition.
