2kW BDOC: Beam Directing Optical Channel
Precision Beam Directing Optical Channel
2kW Beam Directing Optical Channel (BDOC) is an integrated opto-mechanical system built for precise focusing, stabilization and target acquisition of high power laser beams across a 50m to 1500m operating range. A 170mm clear aperture laser beam director sits at the core of the assembly, engineered for demanding field conditions where alignment stability and repeatable performance are non-negotiable.
What is 2kW BDOC?
The 2kW BDOC brings together four functional subsystems, a laser beam director, an auto focusing system, a laser beam stabilization system and a target acquisition system, inside a single opto-mechanical housing. The laser beam imaging camera and target acquisition optics are aligned parallel to the high power laser beam axis, so the system tracks and stays locked on target as range and conditions change.

Opto-Mechanical Assembly
The main mechanical housing carries every mirror and lens mount, the laser collimator mount, zoom lens assembly mounts, camera mounts and the FSM mount. This structure is built to hold optical alignment across all subsystems under real-world operating conditions.
Target Acquisition System
A Day/Night camera with a zoom lens assembly recognizes targets as small as 10cm x 10cm from a range of 250m, giving the system reliable target lock across varying light conditions.
Laser Beam Stabilization System
Beam stabilization holds accuracy to 10mrad. A NIR camera paired with a zoom lens assembly images the focused laser spot from 50m to 1500m, feeding a high bandwidth Fast Steering Mirror (FSM) operating in closed loop with the camera to actively counter drift and hold the beam on target.
Auto Focusing System
The input lens assembly rides on a motorized linear stage, adjusting focus automatically based on live range data from the Laser Range Finder (LRF). This keeps the beam in sharp focus as target distance changes, without manual intervention.

A Beam Directing Optical Channel is an opto-mechanical system that focuses, stabilizes and steers a high power laser beam onto a distant target. It combines a laser beam director, auto focusing system, beam stabilization system and target acquisition system in one housing.
The 2kW BDOC operates across a range of 50m to 1500m.
The laser beam director uses a 170mm clear aperture objective lens assembly, paired with a matching 3-lens input lens assembly, for precise focusing of the high power laser beam.
The input lens assembly is mounted on a motorized linear stage that adjusts focus automatically using live range data from the Laser Range Finder (LRF), so the beam stays focused as target distance changes.
The laser beam stabilization system holds the beam on target with an accuracy of 10mrad, using a NIR camera and a high bandwidth Fast Steering Mirror (FSM) working in a closed loop.
The FSM operates in closed loop with the NIR camera to actively correct beam drift and keep the focused laser spot locked on target.
The target acquisition system, using a Day/Night camera with a zoom lens assembly, can recognize targets as small as 10cm x 10cm from a range of 250m.
Two camera systems are integrated: a NIR camera with a zoom lens assembly for beam imaging and stabilization, and a Day/Night camera with a zoom lens assembly for target acquisition.
