What are autocollimators used for?

An autocollimator is an optical instrument for non-contact measurement of angles. They are typically used to align components and measure deflections in optical or mechanical systems.

What can be measured with an autocollimator?

An autocollimator is an optical device for making angular measurements. It measures microscopic angular differences or deviations to check various properties such as straightness, parallelism, and deflection.

What are the advantages of photoelectric autocollimator?

Advantages of Autocollimators:

  • It has very high accuracy.
  • It can measure wide range angle.
  • It is very easy to set up and operate.
  • Calibration traceable to international standards.
  • It Can be used to see the result visually or electronically i.e in a computer screen.

Which meter is used for alignment?

The Alignment Meter can measure tolerances and errors in mechanical devices with high precision. An Alignment Meter head is rigidly mounted perpendicular to a traveling carriage, and a laser is aligned towards the detector to define a straight optical path.

What is alignment metrology?

Alignment. Alignment involves the evaluation of the geometric orientation of various components of a system by capturing 1- or 2-dimensional data points related to the positions of those components.

What is the main use of steel cube reflector in autocollimator *?

What is the main use of steel cube reflector in autocollimator? Explanation: Steel cube reflector can be used as a general purpose reflector. It can be used for providing a 90 degree angle standard in three planes. It can be used for setting or checking perpendiculars.

What is the use of autocollimator in Mechanical Engineering?

An Electronic Autocollimator is seldom used in the measurement of straightness of machine components (like guide ways) or the straightness of lines of motion of machine components. Flatness measurement is usually performed by measuring straightness of multiple lines along the flat surface.

What are the limitations of autocollimator?

The Autocollimator range For measuring angle, straightness, flatness, squareness and parallelism At long working distances only a portion of the target graticule appears in the eyepiece, owing to the failure of obliquely returning rays to enter the Autocollimator. This can restrict the measuring range.

What is an autocollimator stand?

A multipurpose stand of sturdy construction for general bench use, comprising epoxy granite surface plate, and ground cast iron column and bracket. The Autocollimator clamping bracket has independent clamping and rotational adjustments, enabling the bracket to be turned without disturbing the height adjustment.

Can the Autocollimator be placed directly on the slide?

If this is not possible the autocollimator can be placed directly on the slide. The reflector to be used in conjunction with the autocollimator is mounted onto a carriage, specifically designed for dual axis measurement.
