Описание: This video uses specially-designed small polariscopes built around mineral specimens to project interference figures for muscovite mica, quartz, beryl, phlogopite mica, and combinations of these mineral specimens. There are two styles of device presented. One style lacks a light diffuser, allowing this type of device to function in a manner similar to an optical ring sight. Another style has a light diffuser included. The light diffuser makes these devices better at projecting interference figures, but non-functional as an optical ring sight.
