‘American Bee Journal’ Spetember 2001, page 648 has a dimmensioned drawing of a polariscope.
The dimmensions aren’t real critical. It’s a box roughly 7 inches on each side with a 75 watt light
bulb inside. At the front of the box is 6 inch square sheet of polarizing film. A second sheet of
film with its polarizing plane oriented 90º perpendicular is placed about 6 inches in front of the
other sheet.
‘The Hive and the Honey Bee’, page 909, also shows a polariscope.
Check with photographic suppliers for the polarizing film. I used this company back in 2001 since
I couldn’t find any one locally that carried it:

At the time they carried a ROSCO #7300 19x20 inch polarizing filter sheet. You only need two 6-
inch square pieces though, so you might check to see how many others are interested in making
polariscopes.
