Overview: Axsys Technologies presents a high-speed two-axis gimbal designed for rapid and precise movement. It utilizes high-torque, direct-drive brushless DC motors to achieve ultra-fast point-to-point movement with milli-radian accuracy.
Specifications:- Weight: 10.2 lbs
- Envelope Dimensions: 6.25” W x 7.75” L x 6.50” H
- Input Beam Diameter: 15 mm
- Travel Range: Azimuth: ±160°, Elevation: ±45°
- Resolution: Azimuth: 0.01°, Elevation: 0.05°
- Accuracy: ±0.20°
- Repeatability: Azimuth: ±10 asec, Elevation: ±100 asec
- Max Speed: 90° in 20 ms
- Reflective Coating: Vapor-deposited gold
- Clear Aperture: 0.60” x 1.60” ellipse
Design and Functionality: The gimbal features a gold-coated aluminum mirror supported by a yoke for elevation movement. The azimuth drive system includes a hollow shaft for laser beam passage. High-precision rotary position sensors ensure accurate feedback control.
Electronics and Power: The system operates on a 28V DC power supply, with an optional AC power source. A high voltage capacitor bank provides additional power for high-speed movements. The electronics package includes a 16-bit 150 MHz DSP and dual 16-bit DACs with a settle time of less than 2 microseconds. Serial flash memory allows for field code updates.
