The Zoom 6000 system body tube contains the core zoom mechanism and determines the mechanical nature of your zoom system. Body Tubes may be zoom or non-zoom configurations. Options include:

Manual Zoom Modules: Manual adjustment of the zoom and focus allow the user to change the field of view and regain focus when the sample they are imaging changes size.

Apertures: Allows the user to adjust the amount of light that flows through the system without adjusting light source intensity. 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 1X, 2X, 3X and 4X on the zoom scale

Fine Focus: For applications without separate moving support systems, the Fine Focus body tubes offer focus over a 3mm (coaxial models only) or a 12 mm (non-coaxial models) Fine Focus axial distance at the object. Available in manual and motorized versions.

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.

All zoom lenses come standard with locking screws on zoom and focus (where applicable).
