詳情介紹：
可調(diào)光延遲線（Variable Optical Delay Line）的特點(diǎn)：此款VODL(Variable Optical Delay Line)可調(diào)光延遲線可精密穩(wěn)定的控制光線的延時，精度為150fs。與參考的光路（可選）相比，可進(jìn)行600ps之內(nèi)的可控時延。
The vodl enables a very precise and stable control of light delay. It features a reference arm (in option) that enables the devices to give an absolute precision of the delay in respect with the reference. This delay is independent of the temperature because it is done in air. We can provide also a free space In & Out. For PM versions we can either block the unwanted polarization, the device acting also as a polarizer with high Polarization Extinction Ratio, or keeping both polarizations, while minimizing crosstalk between polarizations

可調(diào)光延遲線（Variable Optical Delay Line）Application:
● Optical paths matching,
● Balancing optical receivers or photodiodes,
● Signals synchronisation,
● Interferometric measurements.
