SOURCE CONDITIONS

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.

HOW TO READ THE MEASUREMENT

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 LR160 specification.

R = c × Δt / 2R: one-way distance · c: propagation speed · Δt: measured round-trip delay

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.

APPLICATION REVIEW

Source-stated application context

Application labels indicate evaluation context, not automatic fitness for a finished system.

The controlled LR160 PDF identifies UAV gimbals, aircraft pods, vehicle turrets, and coastal or border defense systems as application contexts.

This context is bound only to the controlled LR160 document; end-system suitability and acceptance remain subject to engineering review.

INTEGRATION CHECK

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.

TECHNICAL FAQ

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 1064 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.
