When a fraction of an inch is the difference between a precision machine and scrap metal, you don’t want to take chances when it comes to straightness and parallelism measurements. Luckily, Vermont Photonics has an electronic autocollimator that can measure straightness easily and accurately. Measure straightness and parallelism better with the help of the ELCOMAT 3000 Electronic Autocollimator from Möller-Wedel Optical.

First Things First: What Is An Electronic Autocollimator?

Simply put, an electronic autocollimator is an optical device used for non-contact measurement of angles. These devices reflect an image off of a mirror, measuring relative changes in the angle of the mirror as a displacement of the image at the focal plane.

How Does The Measurement Work?

Once you’ve set up your autocollimator, operation is simple enough that a person with no prior knowledge should be able to use it successfully. To measure straightness, slide a base mirror along the rail, stopping at regular intervals to measure the angle. By comparing the angles of the base mirror along the rail, the ELCOMAT 3000 can determine a straightness profile for the rail. Then, you can perform the same operation for the second rail and the ELCOMAT will compare the data from both rails to determine their parallelism.

Benefits of Buying From Vermont Photonics

With its high accuracy and a measuring range up to 25 meters, the ELCOMAT 3000 from Möller-Wedel Optical is the preferred instrument for anyone looking to measure parallelism and straightness. Vermont Photonics also offers calibration for all of our products. Discover more about the Möller-Wedel Optical ELCOMAT 3000. Happy straightening!
