In this paper the design and manufacture of ophthalmic multilayer broadband antireflection coatings with same residual reflective colors on the substrates for different refractive indices have been investigated.Someone need to dispense spectacles in which the two lenses are different optical materials with different refractive indices(e.g.

n

=1.75

n

=1.52)

and the residual reflective colors of the two lenses must remain the same.We designed triplelayer anti-reflection coatings on the substrates which have different refractive indices. The residual reflective colors of these coatings have the same color position in the CIE color chart and have almost the same average reflective brightness.Also

we have found that the quartz crystal thickness monitor is a good method for preparing the AR coatings.
