Laser Rangefinders—Eyesafe

Download PDF

Answering the previously unmet need for a cost-effective eyesafe laser rangefinder (LRF), our new class of compact, eyesafe LRFs offers the highest performance at a fraction of the cost and is sufficiently small and lightweight for handheld, weapon-mounted, or unmanned vehicle integration. This new class of easy-to-operate, easy-to-program eyesafe LRF was custom-developed for use in high-performance consumer, commercial and industrial applications, and for integration with low-divergence diffraction-limited diode-pumped solid-state (DPSS) laser pulses, state-of-the-art InGaAs avalanche photodiode (APD) receivers, and custom CMOS readout circuits to achieve long ranging, even in harsh environmental conditions, with less laser power.

LRF Modules for Original Equipment Manufacturers (OEMs)

Our cost-effective compact LRF modules for original equipment manufacturers allow 1534-nm InGaAs APD laser-ranging capabilities to be integrated quickly and efficiently into optical scopes, electro-optical systems, or weapon systems. These turnkey LRF modules are easily software-programmed and reconfigured. They are calibrated at the factory for optimal operation over a wide temperature range and are rugged to harsh operating conditions, including weapons mounting.

Key Product Features

  • Eyesafe: Class-1M, 1534-nm laser transmitters—ranging from 29-kW to 115-kW peak laser power
  • Long Range: Options for capability of 13 km (single shot) or 21 km (multi-shot) or greater
  • Simple: UART interface and flexible serial programming library
  • High Precision: Better than 500-mm accuracy single-shot variance, even at long range
  • High Beam Quality: Diffraction-limited beam, M² < 1.15
  • Excellent Repetition Rate: Up to 10-Hz pulse-repetition rate
  • Long Lifetime: > 50 million shots
  • Robust: Qualified to guns and other extreme environments
  • Lightweight: Models as light as 106 grams

LRF System-Integrator Kits

Our LRF System-Integrator Kits give system designers a turnkey laser-ranging solution for thermal, electro-optical, and optical scope integration. Each kit includes Voxtel’s ROX™ avalanche photodiode (APD) photoreceiver—which offers best-in-class sensitivity, enabling long-standoff range performance with less laser pulse energy. The ROX photoreceiver is paired with Voxtel’s small-form-factor 1534-nm diode-pumped solid-state (DPSS) erbium-glass laser transmitter, programmable time-to-digital converter (TDC), and programmable controller board. The result is a compact, lightweight highly-reliable ranging module with excellent performance.

These products are not ITAR-controlled.
