Reflected Light DIC Microscopy | Nikon’s MicroscopyU

In a reflected light DIC microscope, the Nomarski prism is oriented so that the interference plane is perpendicular to the optical axis of the microscope (as is the objective rear focal plane). The ordinary and extraordinary wavefronts proceeding to the specimen through a Nomarski prism experience optical path differences that have a magnitude

Inspecting for Porosity with a Microscope | The Home Foundry

Apr 06, 2019 · Here it is under magnification, it physically measures about 1-1/2 MM. Here are some other inclusions on the top of the manifold. This was at the top of the casting. The inlet end of the manifold was pretty clean, compared to the commercial castings. Here is one inclusion I found. I hope to get some better pictures when I get the polishing

Mineral Liberation - an overview | ScienceDirect Topics

Under a microscope, various constituents, such as organic macerals of combustible matter and inorganic minerals of ashy matter, can be seen. The petrological texture of coal indicates the possibility of liberation of different constituents by crushing and grinding. The first step of washing is to crush or grind the coal to liberate the coaly matter from ashy matter, which can theoretically yield complete liberation.

Under the Microscope: How Micromanaging Harms Productivity

May 18, 2017 · Trust is like oil for your department’s engine; without it, the internal parts grind and clatter, creating friction, stress, and an unsafe level of heat. Even the most well-designed parts will eventually fail under those conditions. Collateral Damage. Micromanaging also causes a number of peripheral problems, none of them trivial.
