Dino-Lite AM73915 Series Depth Acquisition with Edge Plus
Introduction
With the EdgePLUS AM4917 and Edge 3.0 AM73915 series, Dino-Lite has taken its Depth Acquisition (DPQ) capability and accuracy to the next level. In contrast to previous models that obtained depths from EDOF stacked images, the AM4917 and AM73915 series’ delicate focus adjustment acquires more accurate depths from the minute increments of change in focus.
Acquire depths of grooves, holes, and other types of topographical variations with EdgePLUS AM4917 series.
Requirements
The DPQ functionality applies to Dino-Lite EdgePLUS AM4917MZT, AM4917MZTL, and Edge 3.0 AM73915MZT(R10) and AM73915MZTL(R10A). Also, please make sure to have DinoCapture 2.0 ver. 1.5.39 or later version installed. If you need to update DinoCapture 2.0, click here and download the latest version.
How to Acquire Depths
- Adjust the focus to a plane of interest. This position will be considered the reference plane as 0.
- To acquire depths, readjust the focus by:
Middle-clicking on a point of interest to autofocus, if necessary, scroll the mouse wheel to readjust the focus.
Or.
Press the “Ctrl” key and scroll the mouse wheel to change focus manually.
This cursor indicates that refocus mode is active and that the focus can be readjusted. A positive focus shift refers to a plane below the reference plane. - To exit Refocus mode, left-click anywhere on the preview window or press the “ESC” key.
DPQs Maximum Depth Range and Accuracy
When performing DPQ, its maximum depth range and tolerance are determined by the magnification being used. This section shows the variations in maximum depths and tolerance at different magnifications in AM4917 and AM73915 models.
Maximum Depth Range
The maximum measurable depths that the device can perform is referred to as maximum depth range. Usually, the higher the magnification, the lower the maximum depth range, and vice versa. The maximum depth range may also vary with depth acquisition direction (upward or downward).
Tolerance
The tolerance is the allowable variance in DPQs. The higher the magnification, the lower the tolerance, and vice versa.
