|
| 3. | Another important application of Canada balsam is in the construction of the Nicol prism.
|
| 4. | The projectors used Nicol Prisms for polarization.
|
| 5. | Nicol prisms were once widely used in microscopy and Polaroid sheets and Glan Thompson prisms.

| 6. | William Nicol ( 1770 1851 ) invented the first polarizing prism, using Iceland spar to create his Nicol prism.
|
| 7. | By 1826, he was already using the integer polarized light, using the then-new Nicol prism as a polarizer.
|
| 8. | When light passes through a Nicol prism its vibrations in all directions except the direction of axis of the prism are cut off.
