A research grade preamplifier is designed to be used as a light-to-voltage converter. The Model 5188A has an InGaAs sensor that responds to near-IR light, while the Model 5188B has a silicon detector that operates in the visible. Sensitivity is switch-selectable with a choice of five settings, allowing amplifications of signals ranging from fractions of a picowatt to 18 mW. Input signal connection is via a FC/PC connector on the front panel. The pream¥runs on batteries, an external power sup
