Spectral Evolution, Inc. --- Detection Modules

Detector Modules:

Si PDA: Silicon Photodiode Array Circuit Board. Includes 128, 256, 512,
or 1024 element UV enhanced Si photodiode array, low noise charge to voltage
preamplifier, 16 bit A/D converter with SPI interface, on board regulator and stable
voltage references. Simple interface requires a single DC voltage, PDA and A/D
clock signals for user configurable sample timing.

InGaAs PDA: InGaAs Photodiode Array Circuit Board. 128, 256, 512, or
1024 element InGaAs or extended InGaAs photodiode array, low noise charge to
voltage preamplifier, 16 bit A/D converter with SPI interface, on board regulator
and stable voltage references. Simple interface requires a single DC voltage,
PDA and A/D clock signals for user configurable sample timing.
