DPQ Depth Information Guide for compatible Edge models
The Depth Acquisition (DPQ) feature provides a quick, non-contact method for acquiring relative depth information from microscopic surface variations, such as grooves, holes, and stepped surfaces. Through controlled refocusing in DinoCapture, DPQ reflects changes in focal plane position and outputs the depth information as a Focus Shift value.
This guide explains how to acquire depth information and provides the related technical specifications for DPQ.
Terminology & Key Actions
The following terms and actions are used in the procedure.
Manual Focus: Adjusting focus via the knob on the Dino-Lite or a compatible stand.
Manual Refocus: Pressing Ctrl + scroll wheel to fine-focus via software.
Auto Refocus: Clicking the mouse wheel to automatically refocus on the targeted position.
Refocus Mode: A state entered as soon as Manual or Auto Refocus is used, allowing for further focus adjustment via the mouse wheel (cursor changes to 
).
Focus Shift: Reflects relative depth from the reference plane. Positive values mean a Downward shift (deeper), while negative values mean an Upward shift (closer to the lens).
DPQ is available with the following compatible EDOF models:

| Paso | Referencia |
|---|---|
| 1 Manually focus on the starting position to define it as the reference plane. |  |
| 2 Refocus on targeted position by either Manual Refocus or Auto Refocus. The Focus Shift value will be displayed below the cursor. Haga clic con el botón central (clic con la rueda del mouse) en un punto de interés para enfocar automáticamente, si es necesario, desplace la rueda del mouse para reajustar el enfoque. o Presione la tecla "Ctrl" y mueva la rueda del mouse para cambiar el enfoque manualmente. La información de profundidad se muestra como el cambio de enfoque. |  o “Ctrl” +   Este cursor indica que el modo de reenfoque está activo y que se puede reajustar el enfoque. Un cambio de enfoque positivo se refiere a un plano por debajo del plano de referencia. |
| 3 Para salir del modo de reenfoque Haga clic izquierdo en cualquier parte de la ventana de vista previa o presione la tecla "ESC". |  |

Focus Shift Range and Tolerance
The Focus Shift indicates the Z-axis displacement from the reference plane, reflecting the relative depth or topographical variations of the sample. The maximum focus displacement and associated tolerances vary by model and magnification. The tables below specify the maximum focus range from the reference plane in both the downward (+) and upward (-) directions.
