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

Nice one

There were lots of scratches on the film

I used these to temporarily convert a regular bright field microscope to a polarizing microscope. You need the top filter above the objectives and below the eyepiece. You need the bottom filter just above the light source. You turn the bottom filter to get the effect you want. It works great with crystals like ascorbic acid crystals. These sheets seem to be high quality and a good value. They are sufficiently thick, but cut easily with scissors to make circles. They have protective plastic on both sides which you peel off. The protective plastic is held on by static cling. There is no adhesive.

Excellent product. Good value. Worked very well.

Working. For 1st GB is enough.

Used this to bring a couple of Bandai Wonderswans back to life, worked great!

El artículo llegó antes de lo programado y en perfectas condiciones. Tal como lo indican en la descripción, contiene 10 hojas de polarización lineal, cada una protegida por ambas caras con una capa de plástico (casi imperceptible a primera vista). Busqué en muchos sitios, y esta fue la mejor oferta, pues otras opciones eran mucho más caras y tardaban semanas en llegar. Las compré para uso en microscopía óptica, para resaltar organismos y estructuras birrefringentes.
