Preamplifiers
-
The primary function of a preamplifier is to extract the signal from the detector without significantly degrading the intrinsic signal-to noise ratio. Three basic types of preamplifiers are available: the current-sensitive preamplifier, the parasitic-capacitance preamplifier, and the charge-sensitive preamplifier. ORTEC manufactures a preamplifier to fit your detector, your application, and your budget.
