Safely enabling acquisition of the most detailed, timely, and
accurate data—at the lowest size, weight, power and cost
The compact ROX OEM series μLRF module is a low-cost easy-to-integrate, easyto-operate micro-laser rangefinder (μLRF) module custom-designed for original
equipment manufacturers (OEMs) of compact ranging systems for commercial,
industrial and military applications.
••
Eye-safe Laser: Many ranging devices use near-infrared lasers or LEDs that
are not eye-safe at the power levels required to generate sufficient return
pulses from long-range targets, under all weather conditions. Our customdeveloped compact monolithic, passively Q-switched, eye-safe 1535-nm
laser—with 100-µJ 2-ns FWHM laser pulses of near diffraction-limited beam
quality at 40 kW of peak power—allows the ROX OEM series µLRF, with a 25mm optic, to image up to 7.5 km in single-pulse mode and over 10 km when
multiple pulses accumulate. A diffraction-limited laser beam with the highest
power in its weight-price class, provides class-leading range and accuracy.
••
Industry-leading Performance with Reduced Size, Weight, Power
and Cost: Measuring precisely at long range previously required inefficient
laser sources with large collection optics, resulting in large, heavy ranging
systems—too large for most consumer and size-sensitive commercial
applications. By tightly coupling our proprietary laser and high-performance
APD photoreceiver with our control and processing electronics, Voxtel makes
possible a new class of ultra-miniature rangefinders that can be embedded
in a wide variety of products. With the Class-1M laser and low-noise APD
photoreceiver, tightly integrated with programmable functionality, the μLRF
achieves noise equivalent power (NEP) of 0.5 nW, with linear dynamic range
of 25 dB and total dynamic range of 70 db, while maintaining excellent
damage threshold levels of 6 MW/cm2. The compact cost-effective design—
which eliminates the need for power-hungry thermoelectric coolers—allows
for smaller, more affordable active systems.
••
Flexible Operation: The photoreceiver has programmable modes to stabilize
gain over a wide temperature range, to optimize ranging performance over
the full temperature range, and to implement other user-programmable
or factory-configured functions. Range-programmable threshold and gain
features allow maintained sensitivity over a large range and optimized false
alarm rates (FARs) for a wide variety of operating scenarios.
