Measuring microscopes for the geometric measurement of objects

Measuring microscopes are mainly used in industry. Here, the systems are used for quality control in production or for checking goods in the receiving department. Toolmakers also use these devices and they are often part of laboratory equipment. The measuring microscopes from the tosag range meet the high requirements for industrial as well as scientific use.

How a measuring microscope works

This type of microscope is used for digital image acquisition as well as video projection of objects. The scale or the crosshairs, which are part of the eyepiece, allow precise and fast measurements without further aids. The visible scale in the eyepiece makes it easy to see what dimensions are being viewed on the object. Very precise movements are possible with the aid of the object stage, which can be moved along the x and y axes. The precision in the movement of the axes is up to 0.5 ?m.

The modern systems work digitally and are often available with fully automatic and electrical controls. In microscopes with digital image processing, also called video measuring projectors, an image converter replaces the operator's eye. These systems automatically focus the measurement points on the object using edge detection mechanics. These video measurement projectors could also work fully automatically in some cases. Predefined tasks can be processed automatically, whereby the system controls the positioning system and forwards the read-out information to the measuring computer. In manual systems, these processes are carried out by the operator. The fully automatic systems also allow the processing of the determined values. In this way, a check with predefined values, for example in production control, is possible. In this way, it can be automatically checked whether the workpieces are within the production tolerance and meet the quality standards.

Image processing systems and smart digital measuring microscopes

The spectrum of digital measuring microscopes ranges from compact small models to complete measuring stations with a wide range of functions for workplaces with high demands. The smaller models require an external monitor or computer to display the images. This enables mobile use of the measuring microscope, as a laptop can also be connected via usb. With other microscopes a display is part of the system.

Measuring microscopes are suitable for different objects and differ accordingly in their technical characteristics. The range of magnification starts with microscopes with a zoom between 0.75x and 5x and extends to over 500x magnification. With a camera adapter, which is available as an accessory, the magnification can be increased to over 1000x. These instruments are designed for particularly fine measurements on very small objects.

The control of the microscopes is very different. There are variants with manual operation that also have monoculars or binoculars for object viewing. Other devices are controlled via a connected computer and the software installed there. Some compact microscopes can be controlled using a directly connected mouse, with the integrated display serving as a screen. This wide selection makes it possible to find a measuring microscope that exactly fits one's needs.

The pure image processing systems no longer have a monocular or binocular. The complete control and image viewing is done digitally via a display. Alternatively, the software of the image processing system takes over the complete measuring process. Statistical process control (spc) is also possible here, which is particularly useful for recurring series measurements, for example in production control. In this way, speed and precision can be significantly increased through process automation.

The image sensors of the measuring microscopes

An important component of the systems are the cameras. They have a significant influence on the quality of the images and the measurement results. A precise image sensor with high resolution thus enables more accurate measurements. This is especially important for small objects. Therefore, ccd and CMOS sensors are used. Especially image sensors based on CMOS technology show clear advantages in practice. They offer precise and automatic functions for exposure control as well as contrast correction, which significantly increases the quality of the images. The resolution of the image sensors is up to 1920x1080, which corresponds to full hd. The images created then have a resolution of 2 megapixels.

Transferring information to it

A great advantage of digital video measuring projectors and measuring microscopes are the interfaces. Systems that have an interface can be connected directly to a computer. The measuring microscopes have outputs of the type usb or rs232. At the usb-interface it is usually also possible to connect a memory stick. Then the images can be transferred directly to the usb-stick. Furthermore, many measuring microscopes have a video output in hdMI format. Using this interface, any monitor with an hdMI input can be connected to the microscope. The images are then shown directly on a large display. This allows detailed viewing of the field of view on the microscope. Furthermore, special software is included with these systems. With this software the direct evaluation of the image data is possible. The software also has techniques for measurements on the objects. Thus, various geometric data can be measured directly on the computer. Among other things, the following actions can be performed:
  • Length measurements
  • Distance between two points
  • Measure diameter and radius
  • Determine the distance between two elements
  • Determine the center of a circle
  • Measure angles
  • Set coordinates to mark areas or points
  • Measure the length, width, and area of an object
  • Determine the length and diameter of an arc
Depending on the model and the size of the object, the measuring accuracy is up to less than 2 ?m.

The software of the measuring microscopes is also compatible with various other programs. Via the export function, the measurement data can be further used in other areas. This can be, for example, Microsoft Excel or Word as well as cad software. For use in cad, the microscope software creates data with coordinates and other required information. These templates are then used to create complete copies of the object in cad, which are required for engineering and similar tasks. The software automatically takes over the measurement of all required geometric information.

Mobile measuring microscopes for use on the road

The mobile measuring microscopes are characterized first of all by their compact dimensions. Such devices weigh hardly more than half a kilogram and are about 20 cm tall. They also function completely without a power supply. This means that mobile use away from a power source is possible without any problems. This is helpful, for example, when checking incoming goods directly at the unloading point.

These mobile measuring microscopes achieve magnifications in a range from 20x to 100x. Depending on the model, the field of view has a diameter between 9.0 and 1.8 mm. Thus, the appropriate measuring microscope can be selected for the intended task. LED spot illumination is also available. The LEDs are supplied with power via AAA batteries.
