AFM Photocell Preamplifier
Our AFM preamplifier is suited for both two- and four-quadrant photocells and embeds 4 very low-noise,
high bandwidth current to voltage converter and amplifiers. The device is shipped as a raw, populated PCB card
in order to allow for proper mounting inside the custom User's measuring heads. The preamplifier is both
compatible with common-ground and common-VCC photocells. We can provide also different types of photocells
which have been proven to be perfectly compatible with this device, as well as assist the User in the choice
of different models. Upon request, the preamplifier can be enclosed in a metal chassis.
