Product Introduction
Wind lidar is an instrument that uses laser technology to measure wind speed and direction(Lidar Wind Measurement).It measures wind speed and direction by sending a laser beam and receiving the reflected laser signal.
Wind lidar has the characteristics of high accuracy, high sensitivity, and strong real-time performance, and is widely used in meteorology,aerospace, environmental monitoring and other fields.
We can offer 1550nm lidar module upon customer's requests.

Note2: 25℃ ambient temperature, the indicator after the laser is started normally, excluding the warm-up phase. Test time 1h.
WARNING: It is forbidden to adjust the reclocking and pulse width of the RF signal while the product has output light. If the re-frequency is unstable, the laser will automatically turn off the pump.
