Product Description
Luna FST-001 is a four-channel piezoelectric-driven optical stretcher. Its core consists of 4 independent piezoelectric actuators (PZT) driving an optical stretching structure, which is integrated with an integrated driving circuit and encapsulated in a small metal housing. It only requires +12VDC power supply. By controlling the PZT voltage, the optical length and refractive index can be changed, thereby achieving optical path delay adjustment. It supports two modes: single-channel independent drive (high resolution) or four-channel combined drive (large stroke). It is compatible with analog signals (0-5V, 30V/V amplification) or 12-bit TTL digital signals control. The standard optical fiber is SMF-28, suitable for a wavelength range of 1260-1650nm. It features low loss, high stability, and flexible control.
Key features
Extremely large optical path delay range: The maximum optical path delay reaches 3mm (air equivalent), and the four-channel combined drive can meet the requirements for large stroke optical path adjustment, suitable for long-distance optical path compensation scenarios.
Dual-mode drive and high resolution: 4 independent PZTs support single-channel independent drive (high resolution) or four-channel combined drive (large stroke). The phase change sensitivity is up to 810π/V (1550nm, four-channel analog input), balancing accuracy and stroke.
Flexible control methods: Compatible with analog (0-5V input, 30V/V amplification) and 12-bit TTL digital signal control. It can be conveniently controlled through function generators, DAC outputs, digital I/O cards, or microprocessors.
