Zoom systems: If the magnification has to be changed frequently then it can be more sensible to use raster zoom systems. Here the working distance inside the zoom range is not changed. In addition the zoom systems have a greater depth of focus than the CV systems. A raster zoom system consists of the zoom optics (6.5x or 12x), an adapter with an intermediate optic of 0.5x to 3.5x, the C-Mount adapter and the camera. It is assembled based on your requirements or based on a joint test carried out at your workshops. The zoom range can be changed by using additional supplementary lenses. The supplementary lenses determine the working distance. The supplementary lenses available are: 0.25x, 0.5x, 0.75x, 1.5x und 2x. The zoom lens without a supplementary lens is calculated as 1x. The working distances which this gives range between 356 mm and 36 mm. The individual click stops are calibrated and stored in the Metric. For the zoom lenses in the 6000 series these are five stops and for the 12000 series a total eight stops. This number is multiplied by each supplementary lens used. For a high degree of process reliability we recommend the use of motorised zoom systems, since with these you cannot forget to switch the lens set in the software. This switch is made automatically through the change of the measurement system in the measurement software. The zoom system is then switched by a stepping motor. The zoom lenses can be provided as desired either with or without a coaxial light reflection. A polarization system can be integrated as an optional extra. A wide number of tripods, guides and individual brackets make available a wide number of possible configurations. XY sliding tables and manual and motorised XY measurement tables are also available. If desired the Z axis can also be delivered motorized (with or without a measurement system). Suitable accessory components allow space-saving installation in machines and devices. The zoom systems can be delivered in angled form or with deflection mirrors. Compile your system together with us and enjoy the resulting simple way of working and the excellent image quality.
