7km Eye Safe Laser Rangefinder 5Hz for 5m² airplane

5km~7km Eye Safe Laser Rangefinder Module of 1Hz continuous and mx 5Hz

5km~7km Laser Rangefinder of typical 5Hz continuous - Evaluating Laser Rangefinder

China TianYing TY-LR71 5km~7km eye safe laser rangefinder designed for integration into compact airborne, maritime and land based optronic systems, provides accurate and effective range performance to dynamic targets in extremely compact unit that weighs only 100 g.

Depending on weather conditions and target characteristics, ranges between 30 m and 13 km can be measured ( beyond 10.8km has been proven). The measuring accuracy is less than 1m. Up to three hundred measurements can be carried out in 60 seconds with a measurement frequency of 5 Hz.

The system is equipped with an external communication connector enabling remote operation and output of electronic ranging information for further processing and display.

The system features an Erbium-glass Diode Pumped sensor with the smallest size, the lightest weight, the highest reliability life and the lowest consumption to ensure performance, that has reached the domestic leading and world advanced level. With its performance, this LRF give you highest performance price rate.

Question:
1, Why many 20km/30km/40km laser rangefinder can not measure tank 10km in standard 23.5km visibility?

Because their 20km/30km/40km is theory data or high reflection large target in ideal visibility condition, even reflection need beyond 80% and visibility need beyond 50km.

2, Why many NATO target 10% reflection 12km laser rangefinder can not measure tank 10km in standard 23.5km visibility?

Because their 10% reflection is not real performance data, 2.3m x 2.3m NATO target is not real tank, or their NATO target effective size is different; normal 2.3m x 2.3m target real albedo is 50% or more.

About test land standard, normal big target typical 20km LRF with 25km visibility, then, normal this LRF can measure 2.3m x 2.3 target about 15km or more, then, 30% albedo 2.3m x 2.3m target is about 10km ~ 12km.


3, Why many laser rangefinder do not show measurement rate details?

Because max rate and continuous rate technology demand is different, such as max 12.5Hz 10 sec to 60 sec, maybe then 5Hz is max 1 min to 3 min with cycle.

Also, when rate have more different, such as 1Hz-5Hz, 1Hz-10Hz, 1Hz-20Hz, 5Hz-25Hz etc, then their working distance have more different too.

About 1.5µm eye safe laser rangefinder, if 1Hz is 10km, then, normal 5Hz is only balance about 80%~ 85%, normal 10Hz is only balance about  70%~80%, when this LRF laser energy is very low, then attenuation speed will accelerate.


4, Why many laser rangefinder price is very cheap?

Because performance is different, for example: one LRF is used for bad cable, messy interface, messy wiring etc, then the LRF cost can reduce, even reduce much, but no warranty on performance.

If used for same performance, then our price is very cheap. that is why many laser rangefinder do not show their real main performance data.
