What are autocollimators?
Autocollimators are high -precision devices that use internal optics to measure angles. This tool resembles a telescope, but is located in horizontal orientation for testing purposes. The main purpose of the tool is to align external mechanical devices such as industrial machines, into a perfectly parallel line. These devices come in two different types, including visual and digital versions. After the object is reflected, the light returns to the internal optics of the tool. Any aberration from the perfect parallel position is displayed on a predetermined scale in the autocollimator. The scale is usually measured in the ARC seconds - also referred to as angular distance - to determine the amount of error in the mirror. Ensure the manufacture of optical fibers of these tools ensure that optical lengths are perfectly equal to the best operation. Balancing laser systems, such as systems used to create a smooth concrete road, use laser laser plane to calibrate. BesidesThe production lines with strict leveling needs, such as in the aerospace industry, use autocollimators to align machines and final manufacturing models.
The visual autocollimator depends on the human eye to determine the angular error. The tool is equipped with a eyepiece. Once the reflective surface and the autocollimator are set opposite the other, one notices the reflected light beam over the tool scale through the eyepiece. Any angle error must be modified, which is outside the tolerance for this reflective surface; A person may adjust the surface angle compared to an autocollimator to reduce the angle error. This calibration continues until a visual error is acceptable for a specific reflective surface.
digital autocollimators operate in the same way as visual tools; However, the device has an internal photodettector that senses an angle error than relying on the human eye. Error is an electronHe converted to a visual value on the display of liquid crystals (LCD). Technicians or repair workers can edit the error and restore the autocollimator to ensure the correct alignment.
The main advantage for digital autocollimators is the storage and trackability of data. In addition, the interpretation of visual errors can be very different from the vision and angle of the person's eyesight. The interpretation of digital errors relies on accurate electronics without interpretation irregularities. As a result, a high -accuracy industry can show that their machinery is in line with the specifications, especially if the accuracy is questioned due to a defect or product failure.
