A Newman projection is a drawing that helps visualize the 3-dimensional structure of a molecule. [1] This projection most commonly sights down a carbon-carbon bond, making it a very useful way to visualize the stereochemistry of alkanes.
In chemistry an eclipsed conformation is a conformation in which two substituents X and Y on adjacent atoms A, B are in closest proximity, implying that the torsion angle X–A–B–Y is 0°. [1] Such a conformation can exist in any open chain, single chemical bond connecting two sp 3 - hybridised atoms, and it is normally a conformational ...
The missing wedge results in a lack of resolution in sample depth, as the missing information is mostly along the z-axis. The missing wedge is also a problem in 3D electron crystallography , where it is usually solved by merging multiple datasets that overlap each other or through symmetry expansion where possible.

An exploded-view drawing is a diagram, picture, schematic or technical drawing of an object, that shows the relationship or order of assembly of various parts. [ 1 ] It shows the components of an object slightly separated by distance, or suspended in surrounding space in the case of a three- dimensional exploded diagram.
Camera lucida in use. A camera lucida is an optical device used as a drawing aid by artists and microscopists. It projects an optical superimposition of the subject being viewed onto the surface upon which the artist is drawing. The artist sees both scene and drawing surface simultaneously, as in a photographic double exposure.
The DoF is wedge shaped, with the apex of the wedge near the camera, and the height of the wedge increasing with distance from the camera. [8] When the plane of focus is at a substantial angle to the image plane, the DoF can be small in height but infinite in width and depth. The sharpness gradients are at an angle to the line of sight.

A petrographic microscope, which is an optical microscope fitted with cross-polarizing lenses, a conoscopic lens, and compensators (plates of anisotropic materials; gypsum plates and quartz wedges are common), for crystallographic analysis. Optical mineralogy is the study of minerals and rocks by measuring their optical properties.
