Abstract
In general, such methods as interferometers or wavefront sensors are commonly used for
testing of an optical system and optical components. In these cases, the surrounding environments
are unlikely to affect the measurements. On the other hand, intraocular lenses of hydrophilic
materials with special properties experience a certain difficulty in testing the optical properties.
An intraocular lens is dried in the air, which causes deformation and changes the optical
characteristics such as index of refraction and thickness. Thus, it is hard to measure the optical
characteristics of an intraocular lens by using common methods. In this study, a special structure
is used for measuring of the transmission wavefront aberration and effective focal length of an
intraocular lens of hydrophilic materials by using a Shark-Hartmann sensor among the various
measuring methods. As an application of this measuring method, this study shows a simple method to
measure the index of refraction of unknown liquids with a plano-convex lens with a well known index
of refraction. Also, this method is used to measure the optical properties of a plano-convex such as
index of refraction and curvature by using a liquid with a well known index of
refraction.
