Low-Noise DC Bias
-
Imaging devices, such as CCDs, IR FPAs, and CMOS image sensors, require DC bias with very low electrical noise to prevent contamination of the image. Image quality can also be enhanced by carefully tuning each bias voltage to extract the maximum signal/noise ratio out of an array. Pulse Instruments has decades of experience providing DC bias supplies with the flexibility required tocharacterize and test a variety of devices while maintaining the noise immunity required for satellite and astronomy applications.
