Motorized zoom lenses offer some great advantages. Imagine the practicality and cost-effectiveness offered by a motorized zoom lens compared to a system design that requires both the camera and lens to move in order to see more detail.
NavitarT has developed a motorization design, available on their 12X and Zoom 6000 systems, that integrates magnetic Hall-Effect sensors. Incorporating the Hall-Effect, discovered by Edwin Hall in 1879, created solid state sensors with no moving parts. A magnetic field is utilized to trigger a pulse in a semiconductor circuit. Unlike photoelectric sensors, Hall-Effect sensors can accommodate harsh, dirty or dusty environments, ambient room light, or variation in system voltages.
Specifications:
- LabVIEW and Windows user interface
- Controlled via serial RS-232 or USB
- Table top or board level control system
- Motorize the zoom and focus axis, or just the zoom
- Three different motor types available:
- 2 Phase Stepping Motor (Faulhaber)
- 5 Phase Stepping Motor (Oriental, Vexta)
- DC Servo with Encoder (Faulhaber)
- Hall-Effect Solid State Sensor Technology (a trademarked Navitar feature)
- Unaffected by ambient light
