Polarizing Film Sheet - set of 10, Model: 93493, Gadget & Electronics Store

Polarizers go completely black when crossed( which is a good thing ) . Will be modifying these to fit a microscope to teach polarizing light microscopy . Will buy again . Recommended

If you drive an older car in a hot climate like Florida, Arizona, Texas chances are your car radio or dash display has 'whited out' Before spending $100's replacing them, try one of these small polarized filters. Usually what causes the LCD display to white out is the polarized film it comes with gets burnt off from years in the sun. I used one on my 2004 Acura LCD info display and the characters came back like magic!

easily scratched but these fit good over most cameras especially indoor security cameras to reduce glare in the window.

Used these to fix my Yamaha LCD Tachometer. The lcd screen was no longer readable and the outer piece of film had curled up. I gambled $10 that I could do it myself vs $250 for a new tach. I won. These are the perfect size for doing the job. I still have enough left over to do more gauges. Fix your lcd screens yourself. Dont throw them away and buy new. It's really not that hard. If you're gonna toss it try and fix it first. You have nothing to lose.

I have an old Nikon upright compound microscope that I am using to look at collagen fibrosis in heart tissue. However, it was missing its polarizer and analyzer. I bought this and cut one sheet into two circles. One was placed in the base of the condenser above the light source. The other one was glued onto a metal circle and then placed above the specimen on the slide. By turning the top filter, I was able to see collagen birefringence perfectly!

Got for use as a science project but see potential use for photography or other applications but sheets are very small and didn't seem worth it overall but was the most affordable option out there. FYI seller, not everyone needs 10 sheets or wants that specific size.

These were not the size that was in the description! What I received was 8cm x 8cm (about 3 1/8" x 3 1/8") when I bought mine, the description said 4.17"x 4.53" (Feb 2024)

I purchased these filters for demonstrations in my physics classes. From each 8 cm x 8 cm square, I cut four smaller squares, which were still sufficiently large enough for my purposes.In most of the images, I am holding 8 cm squares that still have their protective films on.Pairs of filters did a good job at blocking light when their axes were turned 90° from each other.An individual filter noticeably cut down on the glare of light reflecting off of the linoleum tiles in my classroom (I've included a photo of the polarization axis parallel to the floor, and another perpendicular to the floor, for comparison).
