TianYing is the most innovative made of mature, leading and advanced 5km~50km 1Hz~20Hz laser rangefinder, 20mJ~400mJ laser designator rangefinder, accuracy measuring tracking systems, 300mm~2000mm focal length achromatic coaxial zoom spotter CCTV camera sights, electro-optical targeting systems, telephoto thermal cameras etc.
China TianYing TY-LR88 miniaturized 1570nm 20km eye safe laser rangefinder module of 5Hz for 10m² plane. Developed for modern optronic reconnaissance and target tracking systems that require a high repetition rate of measured ranges from fast moving small targets.
Depending on weather conditions, measurement frequency of 5 Hz can be up to a few minutes, measuring accuracy is 1m, working high temperature is +70ºC.
The LRF-20km leveraged the lastest technology to construct this remarkably compact, exceptionally accurate rangefinder, hence customer enable very easy integration into ships, land vehicles or aeroplanes platforms, inclduing camera system, fire-control system etc.

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.
Also, starting state and stable state measuring range is different too, such as 15mJ-25mJ LRF, starting state is 25mJ, typical stable state is only 15mJ, only many companies are only said starting state, for example, said single pulse laser energy is at least 25mJ.
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 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, Erbium-glass is not competitive 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.
