SBIR’s Pulsed Laser Diode Target Projector is designed to provide a uniform collimated pulsed laser output at 1064nm. It can be used for testing both laser receivers and detectors, and also alignment of quadrant detectors used in laser guided missiles.
The system includes a Newtonian type collimator, laser source and controller, and fiber optic/pinhole target assembly. The system can be operated manually via the front panel of the controller or remotely via an ethernet interface to a PC.
STC-630Z Collimator | |
Clear Aperture | 6 inches (15.24cm) |
Focal Length | 30 inches (76.2cm) |
Wavefront Error | 0.35 waves at 633 nm |
FOV | 2.75º |
Size | 33.5” long x 18.6” wide x 12.5” high (85.09cm x 47.24cm x 31.75cm) |
Fiber Optic/Target Assembly
The fiber optic pinhole target assembly is mounted at the focus of the collimator. The alignment of the target assembly will be done at the factory prior to shipment. Periodic adjustment is not required unless the laser collimator and fiber are replaced or the system receives a severe physical shock. | |
