Supports external synchronization input; the external signal can control the laser emission pattern for coding. Coding method: precise frequency code (eight groups of pre-stored period-code patterns). Coding accuracy: ≤ 2.5 μs.
Dimensions ≤ 116 mm × 52 mm × 96 mm
Weight ≤ 680 g
Electrical characteristics Input voltage: DC 18 V to 32 V The electrical and electronic components inside the laser rangefinder/designator are compatible with the system power characteristics. Average power: ≤ 80 W; peak power: ≤ 120 W After PCB design and debugging are completed, all circuit boards are coated with conformal coating to provide moisture, salt-spray and fungus protection.
External power input requirements When sharing the same power supply with motor or other inductive loads, the laser rangefinder/designator should use a soft-start (3–5 s). At the instant of sudden power-on, the induced voltage generated by motors and other inductive loads at the module input may be several times the nominal input voltage, which can cause over-voltage damage. During power-up, it is recommended to use the dedicated power-on control function of the laser rangefinder/designator to stagger its power-on time from other loads. After other loads have powered up and stabilized, then enable power to the rangefinder/designator. The power input of the laser rangefinder/designator should be isolated from other inductive loads. If conditions allow, a DC filter (30 V / 10 A) can be added at the module’s power input. The power supply for the laser rangefinder/designator shall satisfy the peak power demand. When testing the module alone, with a DC supply voltage of 24 V, the supply current should be greater than 6 A. If the output voltage is lower, the rated output current of the supply should be increased accordingly.
Temperature Requirements High-Temperature Requirements Operating temperature: ≤ +55 °C Storage temperature: ≤ +65 °C Low-Temperature Requirements Operating temperature: ≥ −40 °C Storage temperature: ≥ −45 °C
Vibration Requirements The equipment shall withstand flight-induced vibration and shocks occurring during takeoff and landing. All components shall also meet the environmental conditions of vehicle transport. Vibration spectrum: From 15 Hz to 33 Hz , constant-displacement sinusoidal vibration with amplitude 0.91 mm ; From 33 Hz to 700 Hz , constant-acceleration sinusoidal vibration with amplitude 2 g . Duration: 1 hour per axis in three orthogonal directions (X, Y, Z). Test conditions: The product shall be mounted on the vibration platform in its normal operating configuration and powered on during testing. After vibration testing, the equipment shall operate normally.
Shock Requirements Vertical axis: ≥ 10 g Lateral axis: ≥ 10 g Longitudinal axis: ≥ 10 g Shock waveform: post-peak sawtooth, duration 11 ms ; applied along X, Y, and Z axes , both directions on each axis, 18 shocks in total . Test conditions: The product shall be mounted on the shock test platform in its normal operating configuration and powered on during testing.

Application context

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

The controlled LDR80K1 PDF describes distance measurement and coded laser designation for laser-guided artillery shells, mainly on airborne platforms requiring high reliability.

This context is bound only to the controlled LDR80K1 document; end-system suitability and acceptance remain subject to engineering review.

FAQ

Is 1064 nm visible to the eye? It is infrared rather than ordinary visible light. Absence of a visible beam does not indicate absence of emission or hazard. Do not use visual appearance as an exposure assessment.

Does the wavelength determine the laser class? No. Product classification depends on accessible emission and the relevant assessment conditions. The wavelength is one input, not a classification certificate.

Does pulse energy describe electrical consumption? No. Pulse energy is optical energy per pulse. Supply consumption is an electrical quantity and belongs to its own operating condition in the model documentation.

Are accuracy and resolution interchangeable? No. A reporting increment is not a bound on measurement error. Read each field under its own definition and test conditions.

Can full-angle and half-angle divergence be compared directly? Not without identifying the convention. If the released record does not state it, request the measurement definition rather than silently choosing one.

Can the best figures from different operating modes be combined? No. A rate, duration or stability condition belongs to the mode to which it is assigned. Combining unrelated conditions creates a new, unsupported specification.

Does a cited standard prove certification? No. A citation identifies a framework or test method. Certification or completed qualification needs the relevant report and an explicit statement of the assessed product configuration.

What does a “typical” value mean here? It describes the source record’s representative value, not a newly guaranteed upper or lower limit. A typical entry must remain labeled typical.

Can storage temperature be used as the operating range? No. Non-operating storage and powered operation are different states. Preserve both entries and their qualifiers.

Does a reference paper establish this product’s internal material or design? No. General laser physics is not a bill of materials. Internal materials and construction require a controlled model source.

What should happen when a source unit or field is incomplete? Leave the uncertainty visible and obtain a corrected controlled document. Do not infer a missing unit, test condition or option from the product name.

Where are the sources for this page? The Technical Downloads area contains the model document. The bibliography separates product evidence from general standards and safety information; neither replaces a unit-specific test record.
