The unbalanced diffraction ring, brighter on the side away from the knife indicates some degree of tde, but still not so bad. On the right side the brighter half of the ring looks a little wider than before and
I'll trim it tomorrow give it a warm bath, and press the screen in again. The angle shot shows the lap taking on a glazed surface. I think that is not desirable. I'll try to straighten the sides of the facets too. #152 Vanguard Joined:18 Oct 2018 Loc:Barksdale Posted07 July 2021...
has several advantages including: minimization of the mechanical stress of the milled target; a high degree of being able to determine the amount of material being removed when the material has been suitably characterized; and, if suitably controlled, the minimization of excess heating of the part...
I'm not sure how easy it is to test the hypotenuse of the prisms if they are available, without a reference flat. If tested against each other the fringes are viewed at a distorting angle but it might be worth experimenting with. If suitable the prism should be cemented at its side. D...
In my case, my current 12.5” f/5 gives Foucault readings with huge blurs and error factors so that I find it impractical, but your f/8 mirror will produce crisp, sharp rectangles of light that can result in good Foucault test results to allow you to measure the degree of under or ...
The rate at which convergence occurs is a key metric for assessing the effectiveness of the computational procedure, and it is highly dependent on the real-time correction of TIFs. TIFs are significantly affected by the degree of conformance between the forms of the polishing pad and the ...
When the elements were installed, the different pumping positions contributed equally to the degree of disorder of the air flow in the cavity and did not affect the velocity of the air flow in the cavity. With the element installed, the spatial structure distribution in the cavity changed, and...
