Diode laser rangefinders: extremely compact modules for integration into portable systems

These compact laser rangefinders are small, lightweight and energy-efficient, making them ideal for use in mobile and handheld devices.

Laser range finder group

Jenoptik's diode laser rangefinder modules (DLEM) measure distances to targets precisely and with a range of up to 20 kilometers. With their compact design and low weight of 25 to 160 grams, the devices of the DLEM family are the smallest and lightest rangefinders in their range class.
They are very efficient and consume very little energy in stand-by and operation mode. This makes them perfect for integration into mobile and handheld systems, for example portable observation devices.

The modules operate with 1.5 micron diode lasers and are eye-safe. The wavelength is not visible to the human eye or to image intensifiers. The devices are therefore ideal for tactical use. The laser rangefinders measure a wide variety of targets extremely precise and very quickly – even in poor visibility and under extreme temperatures.

The devices of Jenoptik's DLEM series share the same communication interface. This allows you to use the control software for your devices across all models.

Advantages

  • Robust: High shock resistance and wide operating temperature range
  • Compact: Extremely light and small size of customer solutions possible
  • Durable: Low failure rates and high MTBF reduce total cost of ownership for the integrator
  • Energy-efficient: Low power consumption conserves battery and thus extends operating times
  • Continuous measurement: Track targets thanks to continuous distance measurement at up to 25 Hz
  • Symmetrical beam divergence: Eliminates the need for a preferred mounting position and increases integration flexibility
  • Technologically mature: More than 40 years of experience in the development of laser rangefinders from Jenoptik

Fields of application

  • Observation systems
  • Sensor boxes for vehicles, ships and aircraft
  • Targeting optics
  • Fire control systems
  • Electro-optic tracking systems
  • Satellites and space applications

The DLEM 20LE shares the same 30 g weight and mechanical interface and envelope as the DLEM 20 and can range targets out to 8 kilometers, with an accuracy better than 1 meter. It can range 25% further on small targets compared to the DLEM 20. Thanks to its exceptionally compact size, low energy consumption and robust, shock-resistant construction, the DLEM 20LE module is ideal for handheld and weapon-mounted optoelectronic systems and UAV applications.

Typical applications

  • Handheld observation and surveillance systems
  • Weapon mounted fire control systems
  • Payload for UAV/UGV Gimbals
  • Collision avoidance, landing and docking of payloads in space applications

DLEM 30 – economic and lightweight 14 km rangefinder

DLEM 30

DLEM 30 Laser Rangefinder Module

The DLEM 30 can range to non-cooperative targets out to 14 kilometers with an accuracy of better than 1 meter and a measurement rate of up to 25 Hz.

Its weight of only 95 grams makes the DLEM 30 one of the most lightweight devices within its performance class.
