AverEdge32™ Mounting Configuration
The AverEdge32™ mounting configuration lets you use an edge-based method to
determine transverse strain during testing. This edge-based method is only available
using the 16 mm lens but you can perform dot-based axial and transverse testing using
this mounting configuration with all lenses.
The AverEdge32™ mounting configuration affects both axial and transverse fields of
view, whether you are using dot-based or edge-based methods.
