The lens for ophthalmology which includes the projection insertion body which possesses the production, and the said thin film polarized light splitter of the thin film polarized light splitter and the said thin film polarized light splitter

摘要

Consists of PrTiO₃ has the reciprocity accumulation of the layer and possesses a lower refractive index consists of the material which the layer which including the backing which becomes being the polarized light splitter which, thickness e of these layers₁ and e₂ something related to respective description below: Several 1 (In the above-mentioned formula, as for , it is the wave length which is thought, respectively, n₁ is refractive index of 1st layer, and n₂ is refractive index of 2nd layer)The polarized light splitter which is filled up is offered. As for this polarized light splitter, with the lens for ophthalmology which possesses the insertion body which projects the image facing toward the user it can use.
