3D Test pressure gauge series gives you a choice of two different degrees of accuracy to match your application. All 3D test pressure gauge accuracy figures are real : they include all friction, error, hysteresis, and linearity variations.... Every dial is clearly marked for fast, accurate reading with calibrations covering a 270° arc. Parallax is corrected on the test pressure gauge by a neutral glare-free face and a corrosion resistant stainless steel dial, incorporating a polished mirror band. 4, record 3, English, - test%20pressure%20gauge

pressure gage: An instrument for measuring fluid pressure. A pressure gauge usually registers the difference between atmospheric pressure and the pressure of the fluid being measured by indicating the effect of such pressures on a measuring element (as a column of liquid, a bourdon tube, a diaphragm, or other pressure-sensitive device). 5, record 3, English, - test%20pressure%20gauge

[The Ronchi test] uses a grating of fine parallel lines to test the deviation of a mirror from its correct figure. The grating is put in front of the eye after removing the eyepiece and pointing at a star. The lines should appear straight for a spherical mirror. 1, record 4, English, - Ronchi%20test

More efficient than the Foucault knife-edge test, [the Ronchi test] examines curved mirrors by using a transmission grating with 40 to 200 lines per inch in place of the knife-edge, and a section or slit of this grating in place of the pinhole source. 1, record 4, English, - Ronchi%20test

La qualité de la surface réflectrice a été testée à l'aide du classique test de Foucault. [...] L'observation d'une surface polluée d'ondes avec un test plus évolué, un test de Ronchi par exemple, donne lieu à une trop grande densité d'information, ce qui devient presqu'impossible à interpréter. 2, record 4, French, - test%20de%20Ronchi

L'inconvénient [du test de Ronchi] est son manque de précision. Contrairement au test de Foucault, le test de Ronchi n'est pas pratiqué au foyer de l'instrument. Pour gagner en précision, il faut d'une part augmenter le nombre de traits au mm [de la trame] et se rapprocher du foyer. Dans ce cas les phénomènes de diffraction sont prépondérants et rendent l'interprétation de l'image impossible. On ne peut donc pas estimer de façon sûre et quantitative une aberration sur le front d'onde avec ce genre de test. 3, record 4, French, - test%20de%20Ronchi

Le test d'Hartmann [...] permet de mesurer les déviations de la surface d'un miroir par rapport à une surface théorique. Le test fait en laboratoire s'effectue au centre de courbure du miroir. La méthode consiste à placer une source lumineuse sous le centre de courbure et à fragmenter son front d'onde avec un écran perforé placé juste au-dessus du miroir. On peut alors recueillir sur une plaque photographique, située au-dessus du centre de courbure, la réflexion des petits segments du front d'onde. L'emplacement de ces images, par rapport à ce qu'il devrait être si la surface du miroir était paraboloïdale, nous permet de reconstruire le front d'onde, soit la forme du miroir. 1, record 5, French, - test%20d%27Hartmann

Cette méthode pour tester un miroir consiste à placer une source ponctuelle ou une fente étroite dans le plan du centre de courbure du miroir mais très légèrement hors axe. En plaçant une lame exactement à l'endroit où sont réfléchis les rayons lumineux provenant de la source, on peut déterminer la forme de la surface réflectrice. Si la surface est parfaitement sphérique, tous les rayons reviendront exactement au centre de courbure mais légèrement hors axe aussi. 1, record 6, French, - test%20de%20Foucault
