| 1 | The composite materials are characterized by polarizing microscope and infrared spectrum. | |
| 2 | With slight modification this kind of polarizing microscope can be used as gem microscope. | |
| 3 | Oh, and not to mention, they use anti-fog polarized lenses which block out 99% of glare. | |
| 4 | In the design of a polarized light prism, the optic axis ofcrystal often parallels its transmission surface. | |
| 5 | Instrument testing, usually by polarizing instrument to test the structure of its crystals, through the refractometer to test its refractive index. |
