Vertical Manual Stages
Frequently Asked Questions
Vertical manual stages and their subset of Z-jacks are used to precisely align an object vertically. The application range of these stages covers spectroscopic measurements, optical alignment, astronomy, bio-medical experiments and instrumentation, laser alignment and more.
The key parameters to consider when selecting a vertical stage are the vertical travel range; maximum height reached; load capacity; baseplate (table) dimensions, and parallelism (the degree of preserved flatness as the translation stage travels.
In short, always operate the stage within the specified by the manufacturer parameter ranges. Never exceed the specified load capacity (as it would cause unnecessary wear and tear). Don’t operate the stage in extreme cold weather unless it is designed for such conditions. The guide rails often use grease that will get damaged outside of normal operating temperature range (hot or cold).
Both vertical manual stages and lab jacks are used to vertically align a sample or an object. Lab jacks, also sometimes called z-jacks utilize a z-type folding brackets (scissors) to adjust the vertical height. In contrast, vertical manual stages often utilize ball bearings or guide rails that are more precise and offer better parallelism and adjustment sensitivity
While lab jacks are in general less precise than vertical manual stages, some lab jack models include double scissor design where the elevating z-bracket mechanism forms double scissors that offer a lot higher stability and better parallelism than a single scissor. This type of design is often seen on lab jacks with larger table size.
