Sciencetech LDA2000 series detectors are available in 512, and 1024 linear pixel array elements. These detectors utilize Hamamatsu's S390X and S838X series NMOS linear image sensor chips, which are sensitive in 200-1000nm spectral range. Such sensors are available in standard, extra large element size, and high infrared sensitivity versions.
 
System includes the following:

• Photodiode array LDA 2000-512-LS detector
• Power supply and all cables and connections required for the system
• A/D Data Acquisition Board For LDA detectors, 16-bit A/D board is recommended. The A/D Data acquisition board occupies one PCI slot inside a Windows based PC computer and can digitize the detector’s analog signal in real-time. The 16-bit PCI A/D board comes with Windows Drivers and software interface to Sciencetech’s SciSpec, Sci-LDA, and Active-X Component Libraries. It has 16 single ended (or 8 differential) 16-bit A/D channels operating at 200kHz with burst mode capability and conversion time of 5µs. The detector analog signal can be scaled to 10V, 5V, 2.5V, 1.25V (software selectable) and is transfered through a 512 sample FIFO buffer to assure no data is lost. The A/D board also has 24 high current digital I/O channels, and three 16-bit counters for use with multi-channel detectors and Sciencetech detector shutter control.
