WebA simple method to examine the optical parallelism between planar end faces of a ruby rod is suggested. When the ruby rod is illuminated by an expanded He–Ne laser beam with linear polarization, the interference pattern due to the recombination of the E and O rays at a Polaroid analyzer shows its optical parallelism. This optical parallelism, which depends … WebParallelism Parallelism of a window can be specified in terms of angle, usually as minutes of arc. Sometimes it is in terms of thickness variation or "run-out". With conventional …
WebThis paper proposes a new method for measuring parallelism of nontransparent flat parts with high accuracy and then builds a submicrometer-level parallelism measuring system. The 3D model of the whole part is reconstructed by thickness and flatness, which are measured respectively. WebA detailed analysis of an interference technique for measuring the parallelism of the two surfaces of a transparent sample is presented. The technique utilizes the displacement of the center of a set of two-beam, high-visibility, nonlocalized circular fringes, which are produced when divergent laser light is incident on the sample, to give a direct measure of …
WebThe parallelism requirement specifies that two lines or planes are parallel. While it may appear to be similar to flatness, the measurement of straightness involves a datum (reference plane or line), and as such a datum plane is secured to the surface plate when measuring. Sample Drawings Using a Dial Gauge WebA measurement technique is described that is capable of producing accurate numerical maps of the parallelism defect of optically contacted Fabry-Perot etalons. A photoelectric raster scan of the etalon transmission intensity distribution is performed at each of three closely spaced etalon tunings, one at maximum on-axis and two at the half-maxima on …

It's just an assumption, for the sake of simplicity. We are just learning the basics of ray optics, so we are simplifying things to our convenience. Lenses don't always need to be symmetrical. Eye lens, as you said, isn't symmetrical. dave and busters 75243WebParallel simply means that the distances between two surfaces, in this case, the front and back planes of the glass component, are constant.
