About This Product
Specimens are viewed between the polariser and the analyser while the graduated rotary stage turns them and gives a reading of their position. Switching from orthoscopic to conoscopic viewing with the Bertrand lens, and sliding retarding plates into the compensator slots, extends the work to interference observations. The body is finished in acid-resistant textured paint. Educational Lab Equipments can supply and export the Laboratory Geological Petrographic Microscope to Armenia, Gambia, Belgium, Tanzania, Guyana and Turkmenistan.
Frequently Asked Questions
Which compensator plates come with the petrographic microscope?
