LDR60K1 60 mJ Laser Target Designator/Rangefinder Module

The LDR60K1 is a compact, airborne-grade 60 mJ laser target designator and rangefinder module designed for modern electro-optical fire-control and ISR platforms. Based on a high-energy 1064 nm solid-state laser and ERDI TECH LTD’s mature rangefinding and coding architecture, it combines long-range ranging, coded laser designation, and robust environmental performance in a lightweight module that is easy to integrate into gimbals, turrets, and pods.

The module operates in both ranging and illumination (designation) modes, delivering ≥ 60 mJ pulse energy with ≤ 0.3 mrad beam divergence, ±2 m ranging accuracy, and a maximum measuring distance ≥ 10 km against large targets, with a valid detection probability of at least 98%. Multiple operating modes are supported, including single-shot ranging, 1 Hz and 5 Hz continuous ranging, as well as short- and long-cycle coded illumination to match the timing requirements of laser-guided munitions.

For weapon guidance, the LDR60K1 outputs distance and status information with every laser pulse and supports precise frequency-coded laser designation. Up to eight fixed code patterns are available, and the user can configure code period and illumination duration through a standard RS-422 interface. The unit also provides cumulative pulse counting, internal temperature monitoring, range gate and first/last target selection, and strict timing control, with laser response time ≤ 800 ms and power-on startup ≤ 10 s.

Designed for airborne and harsh-environment applications, the LDR60K1 is qualified for an operating temperature range of −40 °C to +55 °C, storage from −45 °C to +65 °C, and meets stringent vibration and shock requirements typical of aircraft takeoff, landing and vehicle transport. With an envelope ≤ 116 mm × 52 mm × 96 mm, mass ≤ 680 g, standby power consumption ≤ 5 W and peak power ≤ 120 W at 18–32 V input, it offers an excellent size-weight-power (SWaP) profile for UAV EO/IR turrets, man-portable designators, and armored vehicle fire-control systems. Conformal-coated electronics and built-in self-test (power-on, periodic and on-demand) ensure long-term reliability with a service life ≥ 1,000,000 pulses.
