Area of Science:

  • Optics
  • Materials Science

Background:

  • Standard Visolett magnifiers utilize crown glass (index, 1.523).
  • A new high-index version (index, 1.806) of the Visolett magnifier is now available.

Purpose of the Study:

  • To evaluate the performance of the new high-index Visolett magnifier.
  • To compare the image size enhancement provided by the high-index material.

Main Methods:

  • The study focuses on the optical properties of the Visolett magnifier.
  • Comparison of image size between standard and high-index models.

Main Results:

  • The high-index Visolett magnifier has an optical index of 1.806.
  • It provides 2.49x magnification with a 32mm diameter.

  • The use of high-index material results in a 39% increase in image size.

    • Conclusions:

    • The high-index Visolett magnifier significantly enhances image size due to its material properties.
    • This offers improved magnification performance over conventional magnifiers.
