  • Abstract
  • Look Inside

Investigation is made on the applicability of non-destructive measurement of refractive index distribution of crystalline lenses. Some prelimi-nary measurements were made using cylinders of acrylic acid resin and a crystalline lens of trout as objects. The conclusions are as follows:

1) There is a great possibility to measure distribution in a crystalline lens if we can obtain appropriate immersion liquid having the same value of refractive index as that of its surface.

2) For a crystalline lens having spherically symmetric distribution, rough measurement can be made without appropriate immersion liquid.
