AVR200 and AVR300 User Guide
capability increases the efficiency of feature measurements, feature data manipulation, and reporting tasks with a simple pinch zoom, swipe pan, or double click.
• Advanced Edge Teach : This feature provides improved edge detection performance under a variety of image and lighting conditions. Features with poor edge contrast, or difficult spacing can be captured in a snap using the M3 software manual teach function. • DXF Overlay and FOV Capability : Using the DXF/FOV option pack, you can import DXF files for “comparative style” Go/No-Go feature and part inspection. This includes a live error whisker display for violations of the original DXF tolerance zones. DXF/FOV option pack features include:
Custom DXF crosshair
•
Create feature-based video overlays
•
Import DXF overlay
•
Export features to DXF
•
Pattern teach and recognition
•
Live image “freeze”
•

3.4.5 Lens Options
To maximize versatility, the AVR systems provide numerous lens options including 6.5:1 and 12:1 zoom optics and telecentric lens options from 4X to 0.14X.
• The telecentric lenses that provide micron-level resolution and optical distortion as low as 0.001% across the field of view (depending on the lens) for accurate field-of-view (FOV) measurements. The 0.14X option enables field-of-view measurements which can encompass an entire small part up to 60 x 51 millimeters (2.36 x 2.00 inches) or a feature of a larger part. • Zoom optics provide continuous zoom from 0.40X to 4.7X. Utilize zoom optics to measure large parts which would not fit into a single FOV. Zoom optics are also beneficial for smaller parts where extremely high magnification is required.
The following figure illustrates the 0.14X telecentric lens option. See “System Specifications” later in this document for detailed information on lenses.
