K-Series Laser Rangefinders
FLIR’s MLR-K series laser rangefinders are the smallest and lightest solid state laser multi-kilometer class laser rangefinders available. The units are compact, weighing as little as 115 grams and use less than 1.5 watts (when ranging), making them easy to integrate into handheld systems and stabilized airborne and maritime turrets. The MLR-K series are a cost effective solution for single shot ranging applications. The MLR-2K can range up to 5 measurements per second and the MLR-10K 1 measurement per second making them ideal for precise measurements on moving targets.
We also offer the custom design services and volume manufacturing to meet your specific requirements. FLIR OEM is a merchant supplier and also offers a complete line of VCSEL based illuminators, laser pointers/designators and SWIR imaging products.
