Refractive index is a measure of how light propagates through a material.The higher the refractive index the slower the light travels, which causes a correspondingly increased change in the direction of the light within the material.What this means for lenses is...
The 1.64 refractive index material is in stock at FOC with extremely low birefringence.Birefringence in polymers is predominately the result of the molding process.The OKP plastics are high purity, polyester polymers with refractive indices ranging from ...
