| 31. | Corneal birefringence is eliminated ( in part ) by a proprietary'corneal compensator '.
|
| 32. | In 1987 Menyuk first derived the nonlinear pulse propagation equation in SMF under weak birefringence.
|
| 33. | If a ray in this direction suffers no birefringence, neither will all parallel rays.
|
| 34. | The birefringence of Kochite is . 0340.
|
| 35. | Its birefringence value is 0.007.
|
| 36. | The birefringence means the decomposition of light into two rays when passing through a mineral.
|
| 37. | The absence of birefringence was initially interpreted by Brace as a refutation of length contraction.
|
| 38. | The birefringence is often quantified as the maximum difference between refractive indices exhibited by the material.
|
| 39. | With negative birefringence, the crystals appear yellow in parallel light and blue with perpendicular light.
|
| 40. | COC materials offer exceptional transparency, low birefringence, high Abbe number and high heat resistance.
