DLEM Laser Rangefinder Modules
Compact 1.5 µm Laser Rangefinder for System Integration
Compact and easy to integrate.
Benefits
DLEM laser rangefinder modules measure distances up to
5,000 meters fast and with an absolute accuracy of better
than one meter. Reliable measurement is warrented within
a wide operational temperature range and even under low
visibility conditions (fog, rain, snow).
• Compact, lightweight design & low-power consumption
• Reliable & accurate results under harsh operating conditions
• Wide target reflectivity range (includes retro-reflectors)
• Eye-safe and not detectable with night vision devices
Applications
Extremely lightweight, compact design allows for easy
• Handheld or portable fire control systems (FCS) for
integration into various handheld, mobile or stationary
grenade launchers, air-burst ammunition or RPGs
measuring or fire control systems. Compact design and low
• Sensor plattforms for UAVs
power consumption meet the requirements for light infantry
• Riflescopes for snipers and long distance shooters
equipment. Especially DLEM SR is considered the world’s
most compact laser rangefinder of its class.
Leading Technology by Tradition
DLEM laser rangefinder are suited for use under harsh environmental conditions and in weapon mounted equipment.
Operating at 1.5 µm, the rangefinder are eye-safe laser class 1.
Jenoptik’s expertise in development and production of laser
rangefinder solutions for various applications builds on more
than 30 years of experience – a reliable partner.
