DJI 3km~7km Tank 12km Ship 25km 1Hz 10mins 1570nm Eye Safe Laser Rangefinder

China TianYing TY-LR78 1570nm 25km eye safe laser rangefinder module developed for tracking platforms tasked to acquire small, moving targets, hence the 1 Hz continuous 10minutes measuring rate and the extended range. They can find the range to midsize targets such as 15m x 8m plane to distances up to and even beyond 25km. The LRF-25km 1 Hz is installed in platforms on ships, land vehicles or aeroplanes. Easy integrated to camera system, fire-control system etc, it is ideal for 500mm to 1200mm focus cooled thermal camera system. We leveraged the lastest technology to construct this remarkably compact, exceptionally accurate rangefinder, hence customer enable very easy integration into different platforms. 25km 1Hz continuous 10minutes Laser Rangefinder Module Recommended Use: 1) Optronic surveillance and reconnaissance. 2) Target tracking systems and anti-aircraft systems. 3) Fire control systems for land, air and sea targets. 4) For determination of flight altitudes on airports. 5) To measure the distance of ships from the coast. 6) In general for applications of position determination of moving objects. 25km 1Hz continuous 10minutes 1570nm Eye Safe Laser Rangefinder Mainly Specification:

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.
