• High Stability & Reliability: Full in-house fabrication ensures consistent performance, tight tolerances, and reduced variation across shipments.

• Platform-Ready Interfaces & Integration: With UART/RS-422 communication, host software, and modular design, the product is ready for OEM integration.

• Wide Environmental Envelope: Designed for industrial and military environments, with vibration/shock qualification, temperature extremes and robust optical alignment.

• Flexible Customisation: Range, form-factor, interface and performance can be tailored to customer needs—ideal for system integrators.

Integration of the 1535 nm laser rangefinder module into a system generally follows these steps:

1. Select Module Variant – Based on required range, size, weight, target type and environment (e.g., 3-km mini module, 8-km tactical module).

2. Mechanical & Thermal Integration – Mount module into UAV pod, vehicle turret, or handheld housing. Provide thermal management and optical alignment.

3. Optical Collimation & Alignment – Ensure the transmitter and receiver optics are aligned and divergence meets system specs. Calibration of beam pointing is required.

4. Electrical & Control Interface – Integrate UART/RS-422 with host control computer; implement driver interface, trigger logic, shot count, self-test.

5. Software & Communication – Use provided protocol and test software; integrate TOF distance data into host system (fire-control, navigation, LiDAR scanner).

6. Calibration & Verification – Validate ranging accuracy, maximum range, multi-target detection (up to 3 targets), and environmental performance (temp, vibration).

7. Operational Deployment – Use module in mission operations: ranging, target hand-off, situational awareness, mapping or industrial inspection.

6.1 UAV & Drone Payloads

When mounted on an unmanned aerial vehicle or gimbal pod, the 1535 nm module supports standoff distance measurement, target acquisition and coordinate hand-over. The eye-safe wavelength allows operations near populated areas or manned platforms.

6.2 Vehicle & Turret Fire-Control

In ground vehicles or turret systems, the module provides accurate target ranging for ballistic correction, missile cueing or reconnaissance. Compact size and rugged design ensure adaptation to constrained spaces and harsh conditions.

6.3 Maritime & Coastal Surveillance

For shipborne or shore-based surveillance platforms, the module’s wavelength offers improved atmospheric penetration (fog, haze) and safe operation in maritime zones. Ranging of fast-moving vessels, drifting objects or small craft becomes feasible at extended distances.

6.4 Industrial, LiDAR, Surveying & Mapping

Beyond defense, the module is valuable in LiDAR scanners, industrial inspection systems, mobile mapping vans or robotics. The combination of precision, compactness and eye safety makes it suitable for complex civilian environments.
