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 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. The easy-to-operate, easy-to-program LRFs include an optional attitude and heading reference system (AHRS), allowing accurate geospatially referenced range data.

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.
