Low Input Bias Current Amplifiers (<100 pA)
Low input bias current op amps are required whenever the difference of currents or voltage is small and needs to be measured accurately. These op amps are used so that the signal is not loaded down by the input of the op amps. Low input bias current op amps are critical for interfacing sensors in applications from photodiodes, pH meters, or other electrometer related functions to downstream electronics. Analog Devices has many precision op amps that fit the definition and range of these applications.

Streak Camera
OptoScope S3C-1
The S3C-1 is a streak camera based on a semiconductor sensor. Like tube-based streak cameras, the S3C-1 captures changes in light along a line and records the change over time. To record the intensity values, they are sampled and stored with up to 2 GSamples/sec. The line is 65 µm wide and consists of 200 elements along its 5 mm length. Each element consists of a sensitive photodiode with a downstream amplifier.A new and special camera feature is continuous recording. This makes it possible to take recordings of events for which precise information about the time of their occurrence only becomes available after they have taken place. This "post-triggering" simplifies or allows certain applications.
