Motorized UltraZoom body tubes are designed to be coupled to infinity corrected objectives when higher magnification and higher resolution imaging is required. These Zoom bodies can be accessorized with a variety of motors so that the solution can be automated and controlled with a motor driver.
Navitar’s motorization design integrates magnetic Hall-Effect sensors to reference position location. Users can choose to motorize the zoom and focus axis, or just the zoom. Navitar has three different motor types available:
2 Phase Stepping Motor (Faulhaber)
5 Phase Stepping Motor (Oriental, Vexta)
DC Servo with Encoder (Faulhaber)
Apertures: The aperture function allows the user to adjust the amount of light that flows through the system without adjusting light source intensity. The aperture also can improve depth of field when it is adjusted properly.
Detents: Obtain specific "stops" throughout the zoom range by selecting a body tube with Detents. Typically used in systems where each position requires calibration, detents allow for pre-set stops at 0.58X, 2X, 2.5X, 3X, 3.5X, 4X, 4.5X, 5X, 5.5X, 6X, and 6.5X on the zoom scale.
Fine Focus: For applications without separate moving support systems, the Fine Focus body tubes offer focus over a 3 mm (coaxial models only) or a 12 mm (non-coaxial models) Fine Focus axial distance at the object. Available in manual and motorized versions.
Motorized Drive: Automated, motorized control of the zoom and fine focus can be requested. Accurate and repeatable positions can be achieved. Several configurations exist to allow you to flexible options.
Coaxial Illumination: Coaxial / on axis illumination is most effective when imaging flat specular surfaces. By integrating the coaxial illumination port, a collimated, diffused and uniform illumination source is integrated into a zoom lens.
