Product Description

China TianYing TY-LR85 miniaturized military 30km ~ 40km laser rangefinder module for ship, measure tank 15km. Developed for 750mm f4 lens thermal camera gimbal type targeting system tasked to acquire small, moving targets, hence the 2 Hz measuring rate and the extended range.

The LRF-30km provides 1m accuracy to dynamic targets in extremely compact unit that weighs 850 g, customer enable very easy integration into compact airborne, maritime and land based optronic systems, including camera system, fire-control system etc, it is ideal for 500mm to 1200mm focus cooled thermal camera system.

The model has reached the domestic leading and world advanced level, the price can compete with Europe and North America manufacturers. With its performance, this LRF give you highest performance price rate.

30km ~ 40km miniaturized Military 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 dynamic objects.

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.
