Webb20 apr. 2011 · I finally got my hands on the charts to show UV, Visible, and IR light transmissions in Plexiglass sheet. And, I learned something new today: IR or InfraRed light varies in transmission logarithmically depending on the thickness of the Plexiglas sheet. And, it's not a smooth curve. There are areas of filtered transmission. WebbSapphire is transparent to wavelengths of light between 200 nm and 5 µm, making it an excellent choice for UV and near/mid-IR applications. Sapphire has a refractive index of ~1.76 in the visible spectrum. Below is a comparison of the optical transmission between our sapphire substrates and our quartz-coated glass substrates, showing the ...

WebbFigure 4: Setup of a 3-plate birefringent tuner. A sharper filter response can in principle be obtained simply by using a thicker birefringent plate. However, this causes the transmission minima to be closer in wavelength (i.e., one obtains a reduced free spectral range), so that the laser may not operate at the desired loss minimum.That problem can … WebbThe light may be positioned to allow transmission directly through the stone from below or reflected from above.
