Thus the reflected image is not well defined one, as one bright and other blurred image are observed.

My presentations Profile Feedback Log out. Garden of eden xx funny or not xxx? A vertically adjustable plunger with both titling and lengthwise movements is also housed in the base. We think you have liked this presentation. Harm to minors, violence or threats, harassment or privacy invasion, impersonation or misrepresentation, fraud or phishing, show more.

Eden rolt millionth comparators?

Share buttons are a little bit lower. The optical system of this instrument involves double reflection of light and thus gives higher degree of magnification. This comparator is designed for very high magnification.

The brackets are kept in alignment by a keyway and a spline, and carry an optical measuring head and a tailstock respectively. Why do other students get annoyed if one students asks too many questions to the teacher? The instrument consists of a cast iron base with three levelling screws and a spirit level for setting instrument horizontal. The slight movement of moving block through pointer strip causes the pointer arm to be deflected as shown in Fig.


Eden Rolt Comparator is a Popular Instrument

Dial Indicator Fitted to Pillar stand: Comparatod Privacy Policy Feedback. Inter-changeable heavy and light duty contact arms are provided for internal measuring and a centre cradle for male cylindrical work. Disadvantages of Mechanical Comparators Mechanical comparators have mililonth moving linkages, due to which the friction is more and hence the accuracy is low.

A combination of magnifying principles has lead to the development of a few more types of comparators, which are: If you wish to download it, please recommend it to your friends in any social system.

Electrical and Electronic Comparators Metrology Previous post: It is very difficult to incorporate an arrangement for adjusting the magnification. Answer Questions Why do other students get annoyed if one students asks too many questions to the teacher? Any wear, play, backlash or comarator faults in the mechanical cpmparator used will also be magnified. In the focal plane of the eye-piece, a fine reference line Index is provided and the system of lenses is so arranged that the image of the scale is projected in the same focal plane.

The Optical arragnement comoarator the Zeiss Ultra-optimeter. We will need more information to help you. The mechanisms used in mechanical comparators have more inertia and this may cause them to be sensitive to vibrations. The second objective lens brings the reflected beam from the first mirror to a focus at a transparent graticule containing a precise scale which is viewed by the eye-piece.


Two brackets are mounted on a transverse bar carried through the base. Optical system of Eden Rolt comparator. Data centres and observablesModern Seismology — Data processing and inversion 1 Data in seismology: The transverse comparattor is spiral grooved to allow easy and quick lengthwise adjustment of bracket.

The spider web at the end of the pointer arm is not viewed directly but it is projected through an optical system on a scale as shown in Fig. Optical magnification provides high degree of measuring precision Mp to reduction of moving members and better wear resistance qualities. The projected image of miillionth line on the graticule can be adjusted by means of screw in order to set the zero.

They are usually robust and easy to handle. Its design is simple and economical. After Adam and Eve were kicked out of Eden, how did they survive with the millions of dinosaurs lurking about? The green light then passes to a condenser which via an index mark projects it on to a movable mirror Mi, whence it is reflected to another fixed mirror M2, and then back again to the first moveable mirror.
