Hand held micro shears are very effective for cutting aluminum sheet metal because they can be directed across the sheet with relative ease. They do not generate any where near the heat of an angle grinder so melting of the metal is not a general concern. Noise, sheet vibration and the finish edge quality are common draw backs of power shears.

Waveplate - Wikipedia

2019-6-9 · 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.
