Digital microscopes use a camera and magnified optics to output a live image to a monitor. From the monitor, the image can be observed, captured, saved, measured, and analyzed. Unlike traditional optical microscopes, digital microscopes do not have eyepieces, and multiple people can observe the image at the same time.
数字显微镜的好处188金宝搏下载app
Compared to optical microscopes, digital microscopes have a much larger depth of field.
The depth of field is the z-range that is in focus at one time.
深度的景深使观察更容易，因为可以在不调整镜头或阶段的情况下查看整个样品。当查看表面不均匀或高度跨表面的大幅变化的样品时，深度深度尤其有利。
188金宝搏下载app与光学显微镜相比，数字显微镜提供的工作距离（WD）更大。工作距离是目标焦点时从镜头末端到目标的距离。
The longer the working distance, the farther into the target the user can observe. Even when the lens is tilted for observation purposes, the lens does not come into contact with the sample. This is especially useful when working with samples that have large changes in height or have features on different Z planes.
Most optical microscopes use a revolver for switching between the objective lenses to change the magnification.
On the other hand, 3D digital microscopes commonly use a zoom lens that the user merely needs to turn the zoom ring in order to change the lens magnification.
With the revolver, if the working distance differs among the lenses, the user must adjust the stage and focus every time the magnification is changed. With zoom lenses, the working distance remains constant, so users can change magnification while still keeping the sample in focus.

Analysis of Fractured Metal Surfaces
When observing each of the features of a three-dimensional object, such as fracture surfaces, analysis can take a long time due to the need to adjust the focus many times.
The VHX Series 4K Digital Microscope’s real-time depth composition function allows you to focus across an entire fractured metal surface. This allows for observation and assessment of the many composite features that are present in fractured surfaces, in addition to reducing the time spent adjusting the focus.
Observation, Measurement, and Evaluation of Skin and Hair
当评估表面特征的深度和细度时，特征的高度差异越小，对比度就越少，这使观察和评估变得困难。传统的显微镜根据照明和角度显示不同的图像，并且容易受到反射和较低对比度的眩光。这使得很难观察到浅凹槽，它们可以逃脱检测。
VHX系列4K数字显微镜的多光照明功能可以自动捕获全向照明数据。通过从此数据中选择最适合观察的图像，您可以大大缩短设置照明所需的时间。
Observation of Metal Structures
Observation of metal structures takes time because only a part of the field of view is in focus. Observation and analysis of objects such as this also has a learning curve, which is an obstacle to achieving precise results.
The VHX Series 4K Digital Microscope’s real-time composition interface provides depth composition that allows for quick and easy observation of fully focused images. Additionally, automatic grain size analysis can be performed, eliminating user subjectivity.

188金宝搏下载app从日本基恩士继续th数码显微镜e best solution on the market. KEYENCE created the first digital microscope over 20 years ago, and continuously implements direct feedback from customers into subsequent generations of scientific digital microscopes. This enables KEYENCE to always be on the bleeding edge, providing products that solve real problems that users face.
Digital microscopes, compound microscopes, stereoscopes, metallurgical microscopes, and polarizing microscopes are all commonly used. While the latter four types of microscopes each have a special designated purpose, a digital microscope combines all of these functions into one device, enabling faster throughput and a more efficient workflow.
相比其他类型的显微镜,数码microscopes are characterized by their high observation functionality and ease of use that is independent of the user’s skill level. However, the required performance is quite different, as is the price of the microscope, depending on whether you are using it for personal observation, quality control in manufacturing, or observation for research. Here, we introduce key points to consider when selecting a digital microscope that is suitable for your intended application.
视野的放大和视野（观察范围）
可以通过将客观镜头的放大倍数乘以目镜的光学放大率来计算。在数字显微镜的情况下，由于在屏188金宝搏下载app幕上观察到图像，因此放大倍率是镜头光放大倍数和监视器显示尺寸的产物。该放大倍数称为总倍率，可以使用以下公式计算：
Total magnification = Monitor magnification x Optical magnification
The optical magnification is indicated by the lens scale. The monitor magnification differs depending on the image sensor and monitor size, and can be calculated with the following formula:
监视放大=（以英寸为x 16*的监视器尺寸） /图像传感器的尺寸*
*光学英寸大小
相反，视场的大小（观察范围）与总的放大倍数成反比。例如，考虑显示器上显示10 x 6 mm区域的50倍放大倍率。如果放大倍数增加到100倍或200倍，则显示在监视器上的视场分别降低到5 x 3 mm或2.5 x 1.5 mm。如本示例所示，虽然增加放大倍数可以扩大图像以更好地查看细节，但它也缩小了视野。
A digital microscope has objective magnification, total magnification, and monitor magnification, which means that when selecting a magnification, you must be aware which of these is indicated in catalogs and which part of the observation object you want to study in an enlarged view. Then, you can select the digital microscope with the magnification and field of view that matches your needs.
照明方法
When using digital microscopes, you can encounter unclear views of objects despite using a high-performance lens if the lighting is not appropriate. To solve this problem, it is important to choose the type of lighting that suits the object to be observed.
There are four major types of illumination, and this section explains the characteristics and advantages of each type.
同轴照明
A: Lens, B: Light source, C: Half mirror, D: Object
Coaxial lighting travels in the same direction as the optical path of the lens. With coaxial illumination, the optical axis of the light emitted onto the object and that of the lens are aligned with a half mirror. This mode of illumination is used for observation of mirrored metal surfaces, smooth plastic surfaces, and objects that specularly reflect light, such as semiconductor wafers, as well as when observing differences in structure or surface gloss instead of features.
戒指照明
A: Lens, B: Object
Ring lighting is emitted diagonally from both sides of the lens. This mode of illumination allows for clear capture of contours due to the contrast created by surface features. It is primarily used at magnifications from 50x to 300x for observing objects with rough surfaces or objects with no gloss or luster.
Transmitted illumination
A: Lens, B: Glass plate, C: Object, D: Light source
与透射照明,光从transparent target and passes through the lens into the image sensor. For this reason, lenses with a large depth of field are suitable considering the thickness of targets. This mode of illumination is used for observation of features within a transparent object, emulsions in liquids, and microorganisms.
可变照明
The direction of light can be changed in real time to emphasize the status of features. Light is emitted onto the target and can be adjusted in real time, allowing for observation of fine features.
Monitor display
One of the most useful features of digital microscopes is that more than one person can look at the microscopic image at the same time. This allows for capturing parts of interest as videos and displaying detailed parts on a monitor for visual checking by multiple people, which can facilitate quick sharing of problems.
The resolution of the monitor can vary from around 2 megapixels to 10 megapixels and up. It is important to select the resolution according to the purpose, along with the selection of magnification and field of view (observation range).
Recording/measurement function
Sharing observation data acquired with a digital microscope between different departments for analysis and review requires functionality that supports large storage capacity and networking. Some key factors to consider include whether observation images can be saved, whether measurement magnification and lighting settings can be saved, and the availability of analysis software that measures profiles, areas, and counts from observation data.
Example: contamination analysis
