Measuring function

A majority of Dino-Lite microscopes and Dino-Eye cameras are equipped with 2-dimensional measurement features. These features are integrated in most USB models, while analog (TV) models do not offer such functions. The measurement functions are applied when the magnification rate is entered into the software (automatically for models with AMR) and the appropriate tool is selected in the software and applied to pixels. To increase accuracy, the arrow keys can be used to adjust lines by one pixel. Measurement tools include line, continuous line, fixed length line, edge detection line, point to line, polygon, circle, arc, angle, grid, and various others.

Measurement tips

The accuracy of the measurement is influenced by three factors: (1) the correct magnification, (2) the measurement setup, and (3) the handling.

Calibration methods

Setup tips: Choosing the appropriate background and lighting can improve contrast. It can be useful to choose a light or dark background that contrasts with your subject. Some Dino-Lite models allow you to adjust the exposure. Operation Notes: Use sufficient magnification to prevent the measured dimension from appearing too small on the preview screen. The lower the magnification, the greater the measurement error may be. Here you can see how the magnification ratio matches the field of view: Field of view gallery.

Accuracy

The magnification values printed on the Dino-Lite instrument serve only as reference points. For precise measurements, a calibration standard is included with each model with measurement functions. Before measurement, calibration should be performed in the software together with the calibration standard. The Dino-Lite is an inexpensive instrument with a wide range of functions for various applications. With correct calibration, the measurement results can often compete with those of precision measuring instruments.

Precision is dependent on several factors, including magnification, screen resolution, and proper calibration. Due to the variable magnification of Dino-Lite microscopes, the tolerance varies depending on the magnification applied. For example, a model with standard magnification set to 220x and a screen resolution of 1920x1080 can be expected to have an accuracy of 0.001 mm. When using a model with high magnification at 930x and the same screen resolution, an accuracy of 0.3 µm can be expected. Further examples of accuracy are shown in the following figures.

Schritt 1

Diese Position wird als Bezugsebene als 0 betrachtet.

Schritt 2

Um Tiefeninformationen zu erfassen, stellen Sie den Fokus neu ein, indem Sie:

Klicken Sie mit der mittleren Maustaste (Mausradklick) auf einen interessanten Punkt, um den Autofokus zu aktivieren, und drehen Sie ggf. das Mausrad, um den Fokus neu einzustellen.

oder

Drücken Sie die Taste "Strg" und drehen Sie das Mausrad, um den Fokus manuell zu ändern. Die Tiefeninformation wird als Fokusverschiebung angezeigt.

Anmerkung:

Der Cursor zeigt an, dass der Refokus-Modus aktiv ist und dass der Fokus neu eingestellt werden kann. Eine positive Fokusverschiebung bezieht sich auf eine Ebene unterhalb der Referenzebene.

Schrit 3

So beenden Sie den Refocus-Modus Klicken Sie mit der linken Maustaste auf eine beliebige Stelle des Vorschaufensters oder drücken Sie die "ESC"-Taste.

Tiefenerfassung: Maximale Tiefenreichweite und Genauigkeit

Bei der Tiefenerfassung werden der maximale Tiefenbereich und die Toleranz durch die verwendete Vergrößerung bestimmt. Dieser Abschnitt zeigt die Variationen der maximalen Tiefe und der Toleranz bei verschiedenen Vergrößerungen der AM4917-Modelle.

Maximaler Tiefenbereich

Die maximal messbare Tiefe, die das Gerät erfassen kann, wird als maximaler Tiefenbereich bezeichnet. In der Regel gilt: Je höher die Vergrößerung, desto geringer der maximale Tiefenbereich und umgekehrt.

Toleranz

Die Toleranz ist die zulässige Abweichung bei der Tiefenerfassung. Je höher die Vergrößerung, desto geringer die Toleranz und umgekehrt.

The microscope's software makes measurements quick and easy. With the measurement function, lines, angles, radii and circles can be determined. The measurement results can be exported to Excel with a click of the mouse together with the corresponding image, which enables the creation of a comprehensive measurement protocol. With the AMR function (automatic magnification readout) , the magnification is automatically transferred from the microscope to the software. This reduces measurement errors and increases accuracy. Measurements can be made both in the LIVE image and later in the saved images. Calibrating the microscope is an important step in order to be able to perform accurate measurements. With the enclosed calibration standard, the microscope can be calibrated with ease and automatically. The DinoCapture software guides you through the necessary steps to ensure a reliable calibration. In microscopy, an extended depth of field achieved by the EDOF function can help to capture the smallest details of cells and tissue samples. This is crucial for the diagnosis and treatment of diseases. The microscope is equipped with an advanced front cap system that allows you to work without a front cap and have an even better view of the object under examination. For optimal adaptation to different applications, various front caps are supplied with the microscope (may vary depending on the microscope), which can be easily mounted. By using diffusers, a different type of light scattering can be achieved, which reduces light reflections and thus enables better image quality. Need help finding the right Dino-Lite microscope?

Dino-Lite USB microscopes are a series of different microscopes that can be connected to a Windows computer or Mac PC easily via USB As an alternative to the pure USB models, there is also the wireless series, which can be connected directly to an iPhone / iPad.. The included software enables quick measurement of surfaces and components. The measurement results can be transferred directly to Excel. In addition, the images can be exported in almost any image format for further processing. With up to 5 megapixel resolution, even the small details can be displayed clearly and distinctly. The built-in chipset enables absolutely good colour and image reproduction. Depending on the USB microscope, you can achieve up to 900x magnification. As a rule, normal use is between 50x and 230x magnification. Various functions then round off the overall package of the Dino-Lite microscopes.

The microscope enables precise measurements to be made quickly and easily via the software. With the measurement function, lines, angles, radii and circles can be determined. The measurement results and the associated image can be exported to Excel at the click of a mouse, making it easy to create a comprehensive measurement report. A direct transfer of the magnification into the DinoCapture software is ensured by the AMR function (automatic magnification readout) . This allows measurements to be made both in the LIVE image and later on stored images. An reliable calibration of the microscope is essential to perform reliable measurements. Thanks to the ease of use of the supplied calibration standard and the user-friendly software, calibration can be performed quickly and easily. The software guides you step by step through the calibration process to achieve the best results. By using the EDOF function, images can be captured with an extended depth of field. This technology is particularly useful in product photography to capture small objects with a large depth of field. The microscope has a front cap system that allows it to work completely without a front cap. Front caps are supplied with the microscope (may vary depending on the microscope) and can be easily added to ensure optimal adaptation to the specific application. By using the diffusers, a special light diffusion can be achieved which helps to reduce light reflections. Would you like to find the right Dino-Lite microscope and need help with the selection?
