Amplifiers
Amplifiers are used to amplify the energy output of photodetectors as well as convert their electrical signal for a number of illumination measurement or spectroscopy applications. Amplifiers are digital systems that amplify the low electrical current transmitted by photodetectors to easily detectable levels. Amplifiers also convert photodetectors' electrical current into voltage so that their signal may be read by other digital devices. Amplifiers are indispensable for nearly any light measurement applications by greatly increasing the usability of a detector system.

Solution for High Density I/O Applications
BitBox
The BitBox is BitFlow''s new solution for high density I/O applications. Many machine makers require a large number of computer managed I/O signals for continuous control of the system state. This means controlling devices such strobes, solenoids, actuators, indicators etc. as well as gathering inputs from photo-detectors, switches, encoders and triggers. In general, BitFlow frame grabbers come with a fairly large number of inputs and outputs, but for some system this is simply not enough. Most customers end up purchasing another device to manage the I/O, which adds expense, requires another slot, another driver and SDK, another manual, etc. The BitBox has been designed for just this situation. It is controlled completely from the frame grabber, uses the same API, driver and manuals as the frame grabber. This saves time, money, space, and learning curve.
