## Questions & Answers

**Q: When it says "linear", does that refer to lines of alternating polarization? In other words, might one "hack" a passive 3D display with it?**
A: Light is made of wave-forms that vibrate in all directions, and what polarisation does is to limit those vibrations to only one plane. Imagine you through a pile of old music CDs down a grid in the street, the slits in the grid allows only those CDs to pass through it which are lined up with the slits. So the polarising sheet is somewhat like that, it allows light to pass through it that vibrates only in the plane of the polarisation of the sheet. That is why it is called linear. I have no idea whether this could be used to hack a display, or even whether hacking a display is something that can be done, or why. So I can't answer that part. Hope this helps.

**Q: Is this film adhesive?**
A: Type ST-38-20S is on one side self-adhesive.

**Q: Can I buy 100x150 or 100x200?**
A: Yes, you can buy ST-30-20 polarizer in 10 cm steps. 10 x 20 cm or 20 x 20 cm.screen-tech.eu

### ⭐⭐⭐⭐⭐ Perfect for cost effective polarising microscope filter
*by H***. on 11 January 2021*

### ⭐⭐⭐⭐ Just right for project.

### ⭐⭐⭐⭐⭐ very good
*by S***E on 2 January 2017*

This is very useful for studying transparent objects in polarised light. I need to have both plane-polarised light (one sheet), and cross polarised light (two sheets at 90 degrees to each other), and this product gives these very well. Note that you get only one sheet, despite the photo suggesting you get two. So if you need cross polarised light you either need to buy two sheets (better therefore to buy the larger sheet option of 500 x 100 mm and cut into 100 x 100 pieces) or if you need only a smaller area, then cut the 100 x 100 sheet into four, 50 x 50 mm pieces, so you have some spares! Note this product is likely best treated as if it was a camera lens surface and avoid scratches because if your sample needs to be pressed against the sheet then any photographs will show the scratches, as is the case for geological thin sections in a slide scanner, which is what I used this for. Therefore I keep the pieces carefully in lens tissue in an envelope to protect them and treat them carefully.
