Title Redesign of a ring light in cooperation with another (big) glass / optics company
A big optics company asked Edmund Optics to do a redesign of their ring light products they
sell as part of their microscopic illumination program. This redesign is planned to be the task for
in internship or a bachelor thesis.
Ring light are widely used as microscope illumination.

Sometime it is needed to use additional polarizers with the ring light and the microscope.
Usually, one central polarizer for the objective is used together with a polarizer for the ring light.
Due to the nature of polarizers one half of the emitted light lost, therefor just one half of the
polarizer is just to modify the emitted light of the ring light as shown in Picture 2, A.
Another problem is the long holder tube, the long “snout” holding the central polarizer. This
snout works as a shade for the ring light illumination. So, when using the polarizers, light is “lost”
due to the polarizer nature AND the polarizer mechanics.
The mechanics of the polarizer shall be altered in a way to make the snout a small a possible.
Inspiration might be taken from competitors like shown in picture 2, B.
The proposed solution must also be affordable in the end.
All possibilities for cost savings (e.g. polarizing film only applied to one side of the carrier
material) are therefore interesting.
