Motorized Solutions

Hall Effect Lenses Overview

• Hall-Effect solid-state sensor technology integrated into motorized zoom lenses.
• Hall-Effect sensors are unaffected by ambient light, environmental contamination, and variations in line voltage.
• Motorize the zoom and focus, or just zoom.
• Motorized controllers feature single or dual axis control via serial RS-232 or USB.
• Control systems available as table top or board level for the OEM.
• Software includes Windows interface and National Instruments "VI".

 

Hall Effect Solid State Sensor Technology

• Unaffected by ambient light.
• Unaffected by environmental contamination.
• Unaffected by line voltage

More Robust Design

Navitar’s motorization design, available on the 12X and Zoom 6000 systems, integrates magnetic Hall-Effect sensors to reference position location. Hall-Effect sensors are solid state devices with no moving parts. They are based on the Hall-Effect, named after its discoverer Edwin Hall in 1879. The Hall-Effect sensing mechanism utilizes a magnetic field to trigger a pulse in a semiconductor circuit. Compared to photo-electric sensors, the Hall-Effect sensors are not affected by harsh, dirty or dusty environments, ambient room light, or variation in system voltages.

 

Our motorized zoom lenses include LabVIEW "VI" and Windows user interface. They can be controlled via serial RS-232 or USB. The control system is available as either table top or board level.

 

Users can choose to motorize the zoom and focus axis, or just the zoom. We have three different motor types available:

• 2 Phase Stepping Motor (Faulhaber)


• 5 Phase Stepping Motor (Oriental, Vexta)


• DC Servo with Encoder (Faulhaber)
