K&F CONCEPT 1PCS Linear Polarization Sheet Adhesive Polarizer Linear Polarizing Filter 300 * 200mm

I used these on overhead projectors in a theatre performance. They created the effect just as I wanted and the quality of the film was good for my use.

Utilisé en binôme avec un filtre polarisant sur mon téléphone pour prendre les photos des tatouages que je réalise. Ça fonctionne comme prévu : plus de reflet sur mes photos :)

I was hoping that this film would have a higher extinction factor. Would have been good if the spec was listed somewhere. In the end I would estimated weak polarization selectivity of about 4:1.

Excellent product, did exactly what it said it would, and cheap!

Buon articolo, fa il suo dovere ed è perfetta per la luce che ho preso
