About
Initially, there are two polarizers. You can adjust the angle between those two polarizer by draging the small rectangle area. The intensity of light pass through the polarizer will vary as you change the angle between them.
No light will pass through when there are perpendicular to each other.
However, if you click the "middle piece" check box -- to add another polarizer between those two.
You will be able to see the image if you adjust the angle of the middle polarizer.

For Teachers
Request in email:
realised that the cat seems to be completely lit when seen through a polariser. However, when we observe an object through a single (ideal) polariser, the intensity (and thus brightness) would go down by a factor of two. Maybe something to add, perhaps showing a "clear" cat, and one through polariser(s)?
And while you are add it, give an option to enter the angles manually by keyboard? :-)
Anyway, whatever you are working on, keep up the good work!

None checkbox for no polariser |
![]() |
unchecked None, means polariser 0 and polariser 2 are in path of eye to cat polariser 0 cannot be rotated |
![]() |
when polariser2 is 90 degree of polariser0, total polarization is simulation and observed |
![]() |
when polariser 1 (middle) is 90 degree of polariser 0,total polarization is simulation and observed |
Added new features of none polarisers.
Enjoy.

Middle Polarizer Check Box
Toggling the middle polarizer will create an additional polarizer
(Default - Middle Polarizer Off)
(Middle Polarizer On)
Drag-able Polarizer
Moving the box round the circle will vary the contrast of the image.
(Default View)
This also works for the middle polarizer as well.
