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.
