Flatness Measurement Using Autocollimator

Flatness Measurement Using Autocollimator. Visual autocollimators measure the angle of optically flat (1/4 wave or better), reflective surfaces in arc seconds by viewing a graduated reticle through an eyepiece. The method of determining the flatness deviation of a surface plate, using differential measurements based on electronic levels, an autocollimator or laser interferometer, is.

Measurement adjust specimen to autocollimator in such a way, that one image of the collimator reticle is centered in the eyepiece reticle. An electronic detector is used to measure the deflection of the mirrored image obtained when an image is. 1) position the reflector at the nearest position of the autocollimator till the reflected image of the target cross line is near the center of the field of view of autocollimator eye piece 2) move the reflector to the other end of the table and check that the reflected image is still with in the.

The drawings were obtained from the van keuren co. An autocollimator works by projecting an image onto a target mirror and measuring the deflection of the returned image against a scale, either visually or by means of an electronic detector.

Flatness Testing Is Something Similar To The Straightness Testing.

Measurement of straightness using an autocollimator and reflecting mirror.

The Basic Use Of A Fizeau Interferometer For Measuring The Surface Height Differences Between Two Surfaces Was Described Earlier.

For small angular measurements it provides a very sensitive and accurate approach. It works by projecting an image onto Measurement of the two axes is made using a combination of the

1) Position The Reflector At The Nearest Position Of The Autocollimator Till The Reflected Image Of The Target Cross Line Is Near The Center Of The Field Of View Of Autocollimator Eye Piece 2) Move The Reflector To The Other End Of The Table And Check That The Reflected Image Is Still With In The.

The reflector is moved along the surface to be measured. The longer the focal length of the visual autocollimator, the greater the angular resolution and the smaller the field of view. Checking the straightness of machine tool slideways.

However, A Specified Cell Width And An Extremely Small Cell Gap Are Needed For The Pd Array, Which Cannot Be Satisfied By A Commercially Available Product.

The figure shows several fizeau interferograms with various types and magnitudes of defects. Suitability of the mbas for measuring flatness are also presented. Directions can be measured by the autocollimator.

It Is Also Used For Plane Surface Inspection I.e.

Autocollimator with collimator reticle s 115 (crossline) and eyepiece reticle s304 or s401:::s431 (reticle with graduation) with elcomat direct the measurement is more precise and the measurement time is reduced. The best interferometer for a particular. If the reference surface is flat, then surface flatness is being measured.
