60mJ Laser Target Designer & Rangefinder - High Precision, Long Range
DESCRIPTION
The LDR60K1 Laser Range Finder and Indication System is a cutting-edge device designed specifically for those seeking high-precision target ranging and laser-coded indications. It is capable of achieving precise measurements over ultra-long distances, reaching up to and beyond 8000m, and its effective coverage for target indication also extends to 5000m and more. A notable feature of this product is its extreme lightweight design, with the overall weight controlled within 650g, making it both compact and portable while maintaining excellent performance and stability.
Furthermore, this system specially offers customization of the laser divergence angle, with an adjustment range of 0.35 to 1mrad, allowing for flexible adaptation to the needs of different operational scenarios. The LDR60K1 strictly adheres to internationally accepted standards, ensuring wide applicability and high reliability worldwide. With its outstanding durability, precise measurement capabilities, and compact, portable design, the LDR60K1 Laser Range Finder and Indication System is undoubtedly the ideal choice for professionals pursuing efficient and accurate operations.
The laser range finder and target indicator has the following functions:
- It possesses laser ranging functionality, outputting distance data and status information for each pulse during ranging.
- It responds to laser ranging commands and can stop ranging at any time upon receiving a stop command.
- It performs cumulative counting of laser pulses.
- It monitors temperature and reports the current temperature value to the system.
- It allows for setting the target indication time, encoding, and outputting the selected settings.
- It responds to laser target indication commands, indicating targets according to the set mode and encoding.
- It outputs distance values and status information for each pulse during laser target indication.
- It can perform laser target indication (laser-coded illumination status) at a frequency set by external commands, with a reserved software interface supporting 8 fixed encodings.
- Power-on self-test: Automatically conducts self-tests on relevant items upon power-on, reports the self-test results after completion, and transitions to standby mode.
- Periodic self-test: Conducts periodic tests during the operation of the laser range finder and target indicator without affecting its normal function. If a fault is detected, it reports the self-test results.
- Initiated self-test: Upon receiving a self-test initiation signal from the system, the laser range finder and target indicator tests its functions and reports the results.
