Product Description
China TianYing TY-LR32 1570nm 40km 1~12.5Hz continuous eye safe laser rangefinder enables acquisition of 5m² jet 25km, plane 40km and building up to 60km within 3m accuracy in 50km visibility.
Depending on weather conditions, target characteristics and exact conditions, ranges between 200 m to 60 km can be measured. Developed for integration into modern optronic reconnaissance tracking systems, provides class 1M eye safe to dynamic and fast moving targets, hence the 12.5Hz continuous 10minutes measuring rate and the extended range.

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 the 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 their 2.3m x 2.3m target about 15km or more, then, real 30% albedo 2.3m x 2.3m target is only about 9km ~ 12km.
For example, air to land read 2.3m X 2.3m target 10km, then, real target is including land and 2.3m x 2.3m target, or said this is measure big target distance. this is why some LRF said 28km for 4m x 6m 0.3 albedo vehicle at 28km visibility, then, when measure Phantom 4 drone, only measure 2.5km at 28km visibility, in fact typical 18-20km LRF can guarantee to measure Phantom 4 drone 3km ~ 4.2km in standard 23.5km visibility.
Also, max energy and stable state measuring range is different too, such as 15mJ-25mJ LRF, max energy is 25mJ, typical stable state is only 15mJ, only many companies are only said max energy, for example, said laser energy is not less than 25mJ, normal this is max energy.
In fact, only recognize tank 20km~30km, many 1200mm/2000mm/2200mm/2600mm CCTV camera can not meet in standard 23.5km visibility.
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 for low energy LRF, such as 1Hz-5Hz, 1Hz-10Hz, 1Hz-20Hz, 5Hz-25Hz etc, then their working distance have more different too.
About low energy 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, even 10Hz is balance less than 40%.
4, Why normal mid-long range high rate laser rangefinder do not use for Erbium-glass laser?
Because normal Erbium-glass laser energy is too low, high rate continuous measuring time is too short, especially at extreme operating temperatures.
In fact, if Erbium-glass laser want to meet demand, energy need at least 2mJ, normal need 5mJ to 8mJ.
Then, 5mj~8mJ Erbium-glass can not compete with OPO and Raman shifted.
5, 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.
