Featured sensors and rangefinders

WindSceptor's laser wind and range sensors are the only devices remotely measuring wind speed, direction, and range-to-target. Whether you use rifle-mounted instruments or long-range telescopes, our precision products will have you covered. 


Each instrument fires a series of 1550nm eye-safe laser pulses into the atmosphere. As the laser pulses travel through the air, a small fraction of the laser light is reflected from microscopic dust particles naturally entrained in the air. Sensors detect this reflected light and compute the speed and direction of travel of these dust particles (and consequently the speed and direction of the three-dimensional wind) using the Doppler Principle.


Accurate? The US Army Picatinny Arsenal validates our work.
