| 6H20.00 | Polarization by Reflection | | |
| 6H20.05 | making black glass | AJP 33(4),xxv | Eliminate the reflection off the second surface of a glass plate with a Canada balsam and lampblack suspension on the back side. |
| 6H20.10 | Brewster's angle | PIRA 200 | Rotate a polariod filter in a beam that reflects at Brewster's angle off a glass onto a screen. |
| 6H20.10 | Brewster's angle | 6H20.10 | A 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. |
| 6H20.10 | polarization by reflection | Disc 24-05 | Rotate a Polaroid filter in a beam that reflects off a glass onto a screen. |
| 6H20.11 | tilt the windowpane | 35-6.2 | Reflect plane polarized light off a window pane and vary the angle of incidence through Brewster's angle. |
| 6H20.12 | Brewster's angle with laser | 36-6.2 | Using horizontally polarized laser light, rotate a glass plate through Brewster's angle to observe a null. |
| 6H20.12 | polarization of the laser beam | 36-6.1 | Rotate a Polaroid in the beam of a laser with Brewster's angle mirrors. |
| 6H20.15 | microwave Brewster's angle | PIRA 1000 | |
| 6H20.15 | microwave Brewster's angle | 33-7.12 | A block of paraffin is tilted until there is a minimum of transmitted radiation. |
| 6H20.20 | polarization by double reflection | PIRA 500 | |
| 6H20.20 | polarization by double reflection | 6H20.20 | |
| 6H20.20 | polarization from two plates | Om-16 | Two black glass mirrors - one fixed and the other rotates. |
| 6H20.20 | polarization of double reflection | Om-2 | Reflect light off a black mirror onto a second rotating black mirror to produce extinction. |
| 6H20.20 | double mirror Brewster's angle | 35-6.3 | Two glass plates are mounted in a box at Brewster's angle with the second able to rotate around the axis of the incident light. |
| 6H20.20 | double reflection polarization | O-8a | Direct
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. |
| 6H20.20 | polarization by double reflection | Disc 24-06 | Offset
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. |
| 6H20.21 | Norrenberg's polariscope | L-123 | Light
strikes two black glass plates in succession, each at 57 degrees. Rotate
the second glass plate and replace it with a mirror. |
| 6H20.25 | large scale polarizer | L-125 | A large box with two black glass plates gives an extended source of plane polarized light. |
| 6H20.30 | Brewster's cone | PIRA 1000 | |
| 6H20.30 | Brewster's cone | Om-18 | A black glass cone at Brewster's angle. |
| 6H20.31 | pyramid method | L-124 | Illuminate a
rotatable pyramid made of four triangles of black glass mounted at 57 degrees
with the base with plane polarized light. |
| 6H20.40 | stack of plates | PIRA 500 | |
| 6H20.40 | stack of plates | L-126 | A stack of glass plated at 57 degrees will transmit and reflect light that is cross polarized. |
