In Nov 2009 the CWFG’s meeting featured a presentation on making your own Polariscope. I tracked down a few online tutorials on how to make a polariscope as well:
- YourGemologist.com shows how to make a polariscope from Sunglasses
- Charles Lewton-Brain 1997 wrote a nice tutorial on building a polariscope
- The Gemology Project has an extensive write-up on Polariscopes
- Here is a link to Polarization.com where you can buy polarizing film by the foot! Awesome resource.
- Polar Shop another place to buy polarizing film by the foot who knew?
- Another great resource, kid’s science sites! Check out SciToys.com and their tutorial on Light & Optics
- How to Make Polariscope at Gem Lab Tools
- Here are instructions on building a polariscope for use with glass but it’s the same principal for looking at gemstones and very well done
Have more resources? Let us know in the comments below and have fun building that Polariscope.
