Laser Rangefinder


The ASKION laser modules for distance measurement (DMM) have excellent technical properties as well as cost-benefit-ratio and can be custom-tailored with respect to measuring frequency, pulse energy, and data interface.
At an operational wavelength of 905 nm, the measurable distance is 20 to 3,000 m with a measurement accuracy of +/- 0.5 m. The integrated ASKION evaluation unit can detect tiniest signals. Therefore, it meets the requirements for class 1 lasers or class 1M lasers, respectively, according to EN 60825-1:2015-07.
At measuring frequencies of less than 1 Hz, the measurable distance lies in the range of several kilometers. Even at measuring frequencies in the range of 10 Hz, very weakly reflective objects can be measured at distances of several hundreds of meters.
The start of the measurement and the output of the measuring data is carried out via an UART interface. The range of operating voltage is 1.9 to 5.2 VDC.
