Model-specific conditions and limits
Conditions are retained only when the source states them. They are not reconstructed from a nominal range or wavelength.
Read the controlled model table for its stated target, reflectance, visibility, temperature, rate and acceptance conditions. No additional condition has been inferred for this model.
Pulsed Time-of-Flight Ranging
A pulsed rangefinder estimates one-way distance from the round-trip delay of an accepted optical return. The equation is general engineering context, not an additional LRF1017C specification.
Pulse energy describes emitted energy per pulse; its effect cannot be separated from pulse width, divergence, optical losses, receiver threshold and the stated target/atmosphere conditions. It is not a substitute for a model-specific near- or long-range acceptance test.
Source-stated application context
Application labels indicate evaluation context, not automatic fitness for a finished system.
Product Description
LRF1017C 10km 1535nm Eye-Safe Long-Range Laser Rangefinder Module for Border, Coastal and Mapping Systems
The LRF1017C is a 1535nm Class I eye-safe long-range laser rangefinder module developed as an OEM core for border surveillance, coastal observation, reconnaissance, measurement and mapping systems. The module is supplied without an outer housing and offers multiple electrical interfaces together with PC host software and embedded software, allowing smooth integration into handheld devices, multifunctional systems, vehicle and shipborne turrets, and fixed electro-optical stations.
Operating at a wavelength of 1.54µm±0.02µm with a divergence angle of ≤0.3mrad, laser energy ≥300µJ, a Φ12mm launch lens and a Φ40mm receiver lens, the LRF1017C delivers NATO target (2.3m×2.3m, 30% reflectance, visibility ≥12km) performance of ≥10km, with a minimum range of ≤50m. Ranging accuracy is ±2m, resolution ≤0.1m, precision rate ≥98% and false alarm rate ≤1%, providing stable, repeatable distance data for long-range observation posts, coastal radars with EO heads, vehicle and ship fire-control aids, and mapping payloads.
The LRF1017C supports a ranging frequency from 0.5Hz to 10Hz, so system designers can choose slow update rates for persistent surveillance or higher rates for tracking moving targets. Time-of-flight processing and multi-target detection allow up to three echoes per shot to be reported via the serial interface, enabling first/main/last target logic in complex scenes such as layered coastlines, harbor areas, urban skylines or mixed vegetation and terrain.
Electrically, the module is powered from a DC 12V supply, with ≤1.2W standby consumption, ≤2W average power and ≤3W peak power at 10Hz. A Molex 51021-0500 connector provides a TTL interface with 3.3V RX/TX, a CTRL line (3.3–5V power-on, 0V power-off), +12V and GND, while a J30J pin-in-lead package offers an RS-422 differential interface with separate RX+/RX− and TX+/TX− lines and redundant supply pins, giving integrators the choice between short-cable TTL inside instruments and longer-distance RS-422 wiring in vehicle, mast or tower installations.
Communication uses a master–slave protocol at 115200bps, 8 data bits, one start bit, one stop bit and no parity. Command frames start with 0x55, followed by a command word, length, parameter bytes and an XOR checksum. Core commands include standby (stop continuous ranging), single ranging, continuous ranging with a programmable period in milliseconds, self-test, distance selection and minimum range (blind-zone) configuration, cumulative shot-count query, APD power on/off and serial-number query. Measurement responses return up to three distances (0.1m resolution) plus a detailed status flag byte that reports main/return wave presence, laser status, timeout, APD status and the presence of fore and aft targets, giving engineers rich diagnostic information for system-level health monitoring.
Mechanically, the LRF1017C measures 107×62×72mm and weighs ≤275g, providing a solid mechanical envelope for turret, mast, tripod and integrated payload use. It is qualified for an operating temperature range of −40 to +70°C, storage from −55 to +75°C, and meets MIL-STD-810G impact and vibration test standards, ensuring long-term reliability on border towers, coastal headlands, armored vehicles and patrol craft exposed to harsh environments.
For installations where an external optical window is used—such as weather-sealed coastal cameras or hardened border units—the optical window should use an anti-reflective coating optimized for 1525–1545nm, with ≥99% transmittance and an overall system transmittance of ≥97% after hydrophobic or hard coatings and mechanical integration. Window thickness is typically held within 2–4mm, the emission axis should be aligned within 2–4° of the window normal, and the air gap minimized to reduce absorption and back-reflection, following the geometry guidelines for effective aperture and outer diameter.
With its 10km NATO-class range, 1535nm eye-safe operation, compact OEM format, TTL/RS-422 selectable interface and full PC/embedded software support, the LRF1017C is well suited for border and coastal surveillance networks, long-range EO/IR and thermal imaging systems, reconnaissance and mapping payloads, vehicle and shipborne observation posts, industrial distance-measurement equipment and other platforms that demand reliable long-range distance data in a rugged, integration-ready module.
Confirm short- and long-distance acceptance conditions
- Define minimum distance, target material, reflectance, size and incidence angle.
- Check receiver recovery, optical-axis overlap and strong-return handling at the intended near limit.
- Verify supply tolerance, peak current, grounding, interface levels, connector and timing with the ordered revision.
- For long-distance acceptance, state target geometry, visibility, weather, background and required detection probability.
- Test with the installed window, boresight, field of view, enclosure and thermal path rather than a bare module alone.
- Evaluate accessible emission, labels and failure conditions again for the finished laser product under IEC 60825-1.
Questions to resolve before design release
Does a stated maximum range apply to every target?
No. A stated range must be read with its target and environmental conditions. Dark, small, oblique, wet or partially obscured targets and degraded visibility can reduce received signal.
Does 1535 nm itself establish the laser classification?
No. Classification concerns accessible emission from the finished laser product. The module statement and final instrument assessment are distinct.
Can a long-range claim be used as the minimum range?
No. Minimum-distance behaviour depends on the particular transmit/receive geometry, receiver timing and strong-return management documented for the model and host system.
