  The New FPAS spectrograph provides a turn-key, drop-in solution for femto-second Pump-Probe 2D
Vibrational Spectroscopy. All required components are provided, including a host computer and LabView
based LASPEC software. Simply focus the laser energy into the entrance slit and start acquiring data.
 Infrared Systems Development Corporation has teamed with the J.Y. Horiba Company to integrate a high
resolution spectrometer with detector and acquisition electronics to provide an easy to use system for
complete spectral acquisition. Interchangeable grating turrets allow complete coverage of the mid and
 long wave infrared bands. All components of the spectrometer and data acquisition system are controlled
 by the supplied LASPEC software. The open architecture and supplied source code provide the user with
 unlimited ability to integrate all computer controlled assets with one application.
The FPAS Spectrometer is the most compact imaging spectrometer available. Offering interchangeable triple
grating turrets, automated dual exit port selection and motorized slit and grating positioning. Array and detector
 exit ports are selected by a motorized flip mirror. Many users have collected data with their single element
 detectors and need a method to correlate the previous data with new data acquired with the Array. 
Our Femto-Second Laser Pulse Acquisition System is the heart of the data acquisition system, providing
simultaneous sampling of all array elements and external user-provided inputs.  The FPAS integrates and
 captures detector signals from short pulse, high-energy laser systems with excellent linearity and 16-Bit
resolution from single pulses or up to 1 x106 pulses in sequence, with no lost data.
Coupled with a high performance Infrared Associates Linear MCT Array, the system provides unmatched
 spectral performance. Dual row detector arrays can be used to provide isolated reference and sample paths
through the spectrometer to compensate for variations in amplitude and energy distribution typically associates
 with ultra-short pulse lasers. 
A complete offering of gratings and detectors can meet any application for high-speed pulse acquisition
spectrometry. Our customer support team has experience with many techniques and is ready to assist
with hardware and software support and modifications to suit your need.
