An opaque substance transmits no light, and therefore reflects, scatters, or absorbs all of it. Other categories of visual appearance, related to the perception of regular or diffuse reflection and transmission of light, have been organized under the concept of cesia in an order system with three variables, including opacity, transparency and ...
The light passes the object of interest laterally upwards. When using the Lieberkühn reflector, the opening in the microscope stage is covered with a flat glass plate upon which the specimen is placed. Typically, a dark disc is placed under the object to avoid direct light entering the objective [7]
The opaque projector, or episcope is a device which displays opaque materials by shining a bright lamp onto the object from above. The episcope must be distinguished from the diascope , which is a projector used for projecting images of transparent objects (such as films), and from the epidiascope , which is capable of projecting images of both ...
Swiss mathematician, physicist, astronomer, logician and engineer Leonhard Euler demonstrated an opaque projector, now commonly known as an episcope, around 1756. It could project a clear image of opaque images and (small) objects. [35] French scientist Jacques Charles is thought to have invented the similar "megascope" in 1780.
For example, NASA's Navigation and Ancillary Information Facility defines that a body in the umbra is also within the penumbra.
