Smartphone polarizer

#1 Post by Aslan » Thu Nov 07, 2019 9:57 pm

Hi, I just ordered a smartphone polarizer sheet with the idea of using it to add polarization to my Ortholux. Has anyone done anything similar?

Hi Aslan,
I have used circular polarizer foil from 3D cinema glasses. Used in the right orientation one get quite acceptable polarizers.
The quality of a polarizer shows when you look through crossed polarizers: The fewer light passes, the better the polarizer.
Another criterium is the colour of the polarized light: Is it neutral or is there a blue or green hue.
For simple tasks a very mediocre polarizer works though.
