6H20.05making black glassAJP 33(4),xxvEliminate the reflection off the second surface of a glass plate with a Canada balsam and lampblack suspension on the back side.
6H20.10Brewster's anglePIRA 200Rotate a polariod filter in a beam that reflects at Brewster's angle off a glass onto a screen.
6H20.10Brewster's angle6H20.10A beam of white light is reflected off a sheet of black glass at Brewster's angle onto the wall. A Polaroid is provided to test.
6H20.10polarization by reflectionDisc 24-05Rotate a Polaroid filter in a beam that reflects off a glass onto a screen.
6H20.11tilt the windowpane35-6.2Reflect plane polarized light off a window pane and vary the angle of incidence through Brewster's angle.
6H20.12Brewster's angle with laser36-6.2Using horizontally polarized laser light, rotate a glass plate through Brewster's angle to observe a null.
6H20.12polarization of the laser beam36-6.1Rotate a Polaroid in the beam of a laser with Brewster's angle mirrors.

6H20.20polarization from two platesOm-16Two black glass mirrors - one fixed and the other rotates.
6H20.20polarization of double reflectionOm-2Reflect light off a black mirror onto a second rotating black mirror to produce extinction.
6H20.20double mirror Brewster's angle35-6.3Two glass plates are mounted in a box at Brewster's angle with the second able to rotate around the axis of the incident light.
6H20.20double reflection polarizationO-8aDirect unpolarized light at a glass plate at 57 degrees, then to another plate at the same angle of incidence and perpendicular to the polarized light.
6H20.20polarization by double reflectionDisc 24-06Offset a beam of light by double reflection off glass, then rotate the first glass 90 degrees to obtain extinction. Replace the glass with metal mirrors and no polarization takes place.
6H20.21Norrenberg's polariscopeL-123Light strikes two black glass plates in succession, each at 57 degrees. Rotate the second glass plate and replace it with a mirror.
6H20.25large scale polarizerL-125A large box with two black glass plates gives an extended source of plane polarized light.
6H20.30Brewster's conePIRA 1000
6H20.30Brewster's coneOm-18A black glass cone at Brewster's angle.
6H20.31pyramid methodL-124Illuminate a rotatable pyramid made of four triangles of black glass mounted at 57 degrees with the base with plane polarized light.
