Product Description

The FST-001-B Fiber Stretcher module consists of a length of optical fiber wound on a frame that can be stretched by controlling the voltage applied to 4 piezo elements. This optical module is packaged with a driver board in a metal enclosure. Each of the four piezos can be controlled independently; they can be driven individually for high resolution or collectively for maximum range. The piezo drive voltages can be controlled via either an analog voltage or via a 12-bit TTL signal. Under analog control, the driving circuit acts as a 4-channel voltage amplifier with 30V/V amplification.
