When performing high-precision angle measurements, autocollimators are often used. Autocollimators are optical instruments that are easy for beginners to understand, and when used properly, they enable accurate angle measurements. In this article, we will explain the method of angle measurement using an autocollimator and seven applications for its use. *For detailed content of the column, you can view it through the related links.

Precise angle measurement is an important element in various fields such as machinery and equipment manufacturing, and robot control. However, selecting the appropriate measuring instruments is essential for performing high-precision measurements. This article introduces methods and types of angle measurement, as well as tips for measuring with high precision. *For detailed content of the column, you can view it through the related links.

Measuring the displacement of an object precisely is an important factor in various fields such as machinery and equipment manufacturing, and robot control. When measuring displacement, a displacement sensor is generally used. This article will provide a detailed explanation of the basics, mechanisms, and applications of displacement sensors. A displacement sensor is a device that accurately measures the displacement of an object. This displacement is referred to as "displacement," and the displacement sensor is also called a "displacement sensor." *For more detailed information, please refer to the related links.

An autocollimator that provides innovative precision in straightness measurement. While there are several measuring instruments capable of measuring straightness, an autocollimator can accurately measure the straightness of machines and equipment. This article introduces the method of measuring straightness with an autocollimator and its advantages from a practical perspective. "Straightness" is defined based on JIS B 0621 as "the magnitude of deviation from the geometrically correct straight line of a linear body." *For detailed content of the column, please refer to the related links.

The measuring instruments used for precise angle measurement are mainly displacement meters and laser autocollimators. So, which is better for angle measurement, the displacement meter or the laser autocollimator? In this article, we will compare and explain the angle measurement methods using displacement meters and laser autocollimators. *For detailed content of the column, please refer to the related links.

When measuring flatness, it seems that using a dial gauge is the basic method of measurement. Of course, if you have a surface roughness or contour measuring instrument, that would be fine as well, but it is not portable. Alternatively, in the case of a measurement target placed on the base of a device, it is necessary to temporarily incorporate the measuring instrument into that device, and there are various reliable measurement methods for that. This time, I will introduce a measurement method for flatness and parallelism using a laser autocollimator. *You can view the detailed content of the column through the related links.

The repeatability of laser measuring instruments is influenced by the surface light scattering state of the workpiece (measured object) and the measurement environment, resulting in variations that are not insignificant compared to the catalog values. Generally, there is a tendency for this to worsen, so if quality inspections are set solely based on the accuracy specifications listed in the catalog, the reliability of pass/fail judgments may be compromised. In this column, we will clearly organize the repeatability accuracy of laser measuring instruments. *For detailed content of the column, you can view it through the related links.

Special tools and sensors are required for repairs, maintenance, and optimal condition adjustments tailored to specific purposes. In manufacturing environments, misalignment of the optical axis is one of the key factors that particularly requires attention, as it affects machining precision, measurement accuracy, lens focusing, and quality control. This time, we will explain "optical axis adjustment," which is a primary task of optical engineers, and introduce the related issue of yield reduction. *For more detailed information, please refer to the related links.

In recent years, in the assembly and adjustment process of laser devices, simply using conventional measuring instruments has become insufficient for the field to function effectively. There are various factors contributing to this, but to simplify, it is because the demands for yield have become commonplace, exceeding the field's capacity to respond. This time, I will explain a revolutionary method to improve such black operations. *For detailed content of the column, please refer to the related link.

There are two main modes of reflection: specular reflection and diffuse reflection. Instruments that measure displacement and distance with lasers are designed to primarily correspond to one of these modes. Since each mode has opposing advantages and disadvantages, I will explain how to choose which type of displacement meter to purchase for those who are unsure. As a preface before diving into the main topic, I will discuss the mechanism of devices that measure angles, displacement, and distance with lasers. *For detailed content of the column, you can view it through the related links.
