ZeGage Pro Raised Head: When Do You Need It?

The ZeGage Pro Raised Head option lifts the optical profiler head by 75mm to accommodate taller parts. This article explains when it's needed and how it works.
Quick answer
The ZeGage Pro Raised Head option adds 75mm of vertical clearance for measuring taller parts. Order it at manufacture time if your samples exceed the standard head height.
Why clearance matters in 3D optical profiling
A standard ZeGage Pro head sits at a fixed lower position. For parts taller than that clearance, the head physically cannot focus on the surface. The Raised Head option permanently moves the head up by 75mm, giving you room for larger components without sacrificing measurement quality.
Trade-off: it's a manufacturing-time option
The Raised Head is set during instrument manufacture. You cannot add it later as a field upgrade. If you anticipate needing extra clearance in the future, specify this option when ordering your ZeGage Pro.
Frequently asked questions
- How much clearance does the Raised Head add?
- It raises the maximum part height by 75mm compared to the standard head position.
- Can I install the Raised Head on an existing ZeGage Pro?
- No. The option is set during instrument manufacture and is not available as a field retrofit. Plan ahead: if you might need extra clearance, order the Raised Head with your new ZeGage Pro.
- Does the Raised Head affect measurement accuracy?
- No. The optical path remains unchanged; only the physical head position is higher. Measurement performance is identical to the standard configuration.
Product facts
- Raised Head, ZeGage: The Raised Head, ZeGage option places the 3D optical profiler head in its upper position at instrument manufacture, raising the maximum part height by 75mm. This allows the ZeGage Pro to measure parts that are up to 75mm taller than the standard configuration, expanding your sample range without needing a different profiler.
