General

YZT-CJ-0310F laser range finder module is a laser range finder module developed based on the 1535nm erbium laser independently developed by FOVA. It adopts single pulse TOF ranging mode and has a maximum measuring range of ≥3km. It is composed of laser, transmitting optical system, receiving optical system and control circuit board, and communicates with host computer through RS422 serial port (TTL serial port can be customized), provides host computer test software and communication protocol, which is convenient for users to develop the second time. It has the characteristics of small size, light weight, stable performance, high impact resistance, first-class eye safety, etc., and can be applied to hand-held, vehicle-mounted, pod and other photoelectric equipment.

5. Safety & notifications

• The laser emitted by the ranging module is 1535nm for human eye safety laser, although it is a human eye safety wavelength, but it is recommended not to look directly at the laser;
• When adjusting the parallelism of the three optical axes, the receiving lens must be blocked, otherwise the detector will be permanently damaged due to excessive echo;
• The measuring module is non-airtight, and must ensure that the relative humidity of the use environment is less than 80%, and ensure that the use of the environment is clean and sanitary, so as not to damage the laser;
• The range measurement of the range module is related to the atmospheric visibility and the nature of the target, and the range measurement will be reduced in the case of fog, rain and wind sand. Green leaf clusters, white walls, exposed limestone and other targets have better reflectivity, which can increase the measurement range. In addition, when the Angle of the target to the laser beam increases, the measurement range will be reduced.
• It is strictly forbidden to emit laser to strong reflection targets such as glass and white walls within 5 meters, so as to avoid too strong echo, resulting in damage to the APD detector;
• Do not plug and unplug the cable in the energized state;
• Ensure that the power supply polarity connection is correct, otherwise it will cause permanent damage to the device;
