Summary
| Description |
English: Four photos showing an optical flat test as wringing progresses, using 589 nanometer laser light. The surfaces are perfectly flat relative to each other, to a flatness of λ/10, which equates to a normal deviation of 58.9 nanometers. The fringes begin as thin, parallel lines which widen as the air is slowly expelled from between the surfaces, until only a single fringe remains. At λ/10 the surfaces are not quite flat enough to wring very tightly. |
