LASER RANGE FINDER

OEM Laser Rangefinders for
Precise Long-Range Distance Measurement

The Laser Distance Measurement Modules (DMM) by ASKION offer outstanding technical characteristics, an exceptional price-performance ratio, and are fully customizable regarding measurement frequency, pulse energy, and data interface.

Operating at a wavelength of 905 nm, the measurement range spans from 20 to 3,000 m with an accuracy of ± 0.5 m. The integrated ASKION evaluation electronics enable the detection of ultra-weak signals, meeting the requirements of eye-safe laser safety class 1 or 1M according to
EN 60825-1:2015-07.

At measurement frequencies below 1 Hz, distance measurements in the kilometer range are achieved. Even at frequencies in the 10 Hz range, very low-reflective objects can be reliably measured at a distance of several hundred meters.

Frequently Asked
Questions

How are the ASKION LRF modules integrated?

As pure OEM modules, they are optimized for seamless mechanical and optical integration into your higher-level systems, such as sensor platforms, gimbals, or handheld devices.

Which interface is used?

All modules feature a universal UART interface as standard, making software integration highly straightforward.

Are the modules suitable for high mechanical stress?

Yes, the modules feature an extremely rugged design, withstanding shocks up to 1500 g – perfect for demanding applications.

Can the measurement frequencies be customized?

We cover 0.1 to 10 Hz as standard. Higher or custom frequencies can be flexibly adapted to your specific system requirements.

Are the units suitable for measurements while the sensor is moving?

Yes, the modules are explicitly suitable for operation on moving platforms. The optimal measurement time depends on the speed of movement and the chosen beam divergence.

Is each reported range based on a single laser pulse or an accumulation of multiple measurements?

The range determination is based on an accumulation of laser pulses, utilizing an internal base rate of 10,000 pulses per second. Depending on the selected output frequency, the module uses a fraction or a multiple of this base rate to achieve exceptionally high measurement accuracy and signal stability.

How does the module handle multiple returns (e.g., a tree in front of a building)?

Our modules can detect up to 4 targets simultaneously along the same line of sight. If only a single range is required, the target with the highest return signal strength is selected by default.

What signal and quality data is provided with each measurement?

Each measurement output includes the received signal strength indicator (RSSI). If a return signal is too weak for a reliable measurement, a distinct “0” is returned to prevent misinterpretation by the host system.

Are the modules eye-safe?

Yes, our 905nm laser rangefinders are certified as Class 1 / 1M eye-safe according to EN 60825-1, ensuring safe operation under all standard conditions.

What are the trade-offs of a narrower beam divergence (e.g., 0.9 x 0.4 mrad)?

A narrower divergence can be supplied without any reduction in pulse energy, range, or changes to the laser safety rating. The tighter beam simply requires more precise alignment with the target.

How do low-reflectivity targets or harsh weather affect performance?

Natural targets with low albedo (e.g., vegetation, dark surfaces) as well as strong sunlight, rain, or mist will reduce the maximum operational range. To determine exact performance boundaries for your application, we recommend field testing using our Evaluation Kits.

Does the 905nm technology fall under Dual-Use regulations?

No. Due to the 905nm wavelength, these modules are not classified as Dual-Use goods, significantly accelerating civilian procurement.

Are the ASKION LRF modules ITAR-free?

Yes, all of our laser rangefinders are completely ITAR-free. Designed and manufactured entirely within Europe, our modules are not subject to US ITAR regulations, significantly streamlining international procurement.

When is an End-User Certificate (EUC) required?

An EUC is only necessary if the modules are explicitly intended for use in military or defense applications.

Do we need a non-disclosure agreement (NDA) for technical discussions or OEM integration?

From our side, no NDA is required to provide our standard modules or CAD data. However, if you prefer the protection of a non-disclosure agreement to share your sensitive system details, we are dynamic and glad to review and sign your NDA documents promptly.

How do I obtain the 3D CAD data for our design process?

Simply via our request form. Following a quick verification of your business details, we will send the STEP files directly to your email address.
