## Description

Our 2" square linear polarized filter slide has a 1-3/8” x 15/16” window. Nice for classroom demonstrations and home-schooling use. Made in the USA.

Review: Works well for looking for stress in fused glass. - Some what fragile. Working with the sample piece, use a piece of white glass behind the bottom film then place sample piece on top of bottom film. Place top film in place and look through both films towards a light. You will have to work with the top piece until the films are in correct positions. If you see halos, the glass will not work together..
Review: A good hack for remote control issues - gift! Remote will control multiple TVs in the same room. But thats actually an issue sometimes. Putting these over the IR receiver alleviates that problem. Now the remote has to be pointed at the device... and prevents most errant signals from getting thru.

### ⭐⭐⭐⭐ Well-made, though poorly marked.
*by A***Y on September 26, 2018*

I expected the direction of polarization to be marked on the slide, but it's not. It's easy enough to figure out, but the oversight seems a little silly to me. If you're getting a number of these, be prepared to check the orientation of each one, as it's unknown whether the manufacturer always does them in the same way. Other than that, they worked fine for my intended use (double-slit experimentation).
