Waveplate - Wikipedia

A waveplate or retarder is an optical device that alters the polarization state of a light wave travelling through it. Two common types of waveplates are the half-wave plate, which shifts the polarization direction of linearly polarized light, and the quarter-wave plate, which converts linearly polarized light into circularly polarized light and vice versa.

Geology of Quartz Deposits - Mineralogical Society of America

In some cases the crystals occur on the hanging wall side. Less than 1 lb. of usable quartz per ton of rock mined was reported from various operations over a period of several months. The occurrence stands out as the only described example of usable crystals in a deposit economically productive of metallic minerals. Quartz in Guatemala


1 m wide interval of milky white to blue quartz vein was intersected from 12.24m to 13.24m. The quartz vein had up to 2% sulphide mineralization consisting of semi-massive pyrite and pyrrhotite with trace chalcopyrite. Hole LE21002 – The hole was stepped back on section from LE21001 and targeted beneath the NW Irving and Michelle trenches ...

DRI SOP Pre-firing and Acceptance Testing of Quartz-Fiber ...

This procedure delineates the process for pre-firing and acceptance testing of quartz fiber filters. Quartz fiber filters absorb organic gases from ambient air and organic artifacts from the manufacturing process. By pre-firing the quartz filters before sampling, these absorbed gases and artifacts are reduced to constant, insignificant levels.

Optical fiber - Wikipedia

An optical fiber (or fibre in British English) is a flexible, transparent fiber made by drawing glass or plastic to a diameter slightly thicker than that of a human hair. Optical fibers are used most often as a means to transmit light between the two ends of the fiber and find wide usage in fiber-optic communications, where they permit transmission over longer distances and at higher ...

RP Photonics Encyclopedia - waveplates, quartz, quarter ...

The most common types of waveplates are quarter-wave plates (λ/4 plates) and half-wave plates (λ/2 plates), where the difference of phase delays between the two linear polarization directions is π /2 or π, respectively, corresponding to propagation phase shifts over a distance of λ / 4 or λ / 2, respectively.. Some important cases are: When a light beam is linearly polarized, and the ...
