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
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
Coaxial Illumination: Coaxial / on axis
illumination is most effective when imaging flat specular surfaces. By
integrating the coaxial illumination port, a collimated, diffuse and
uniform illumination source is integrated into a zoom lens.
All zoom lenses, except 1-6000, come standard with locking screws on zoom and focus (where applicable)
