This technique requires that the analyser and compensator be withdrawn, the illumination increased, and the dispersion objective with phase ring in the back focal plane be inserted together with the corresponding phase annulus in the condenser. \u003cbr\u003eDifferent colours will be observed when the fibre is oriented parallel or perpendicular to the vibration \/ polarizer direction. This method is easier to interpret than the objective stop method used by the older ML Series due to the presence of two complementary colours in the same image, so that the wavelength of the refractive index match can be more closely determined. \u003c\/p\u003e","brand":"Auckland Scientific","offers":[{"title":"Binocular Microscope - MT6820","offer_id":58650992214341,"sku":"Meiji MT6820","price":6725.0,"currency_code":"GBP","in_stock":true},{"title":"Trinocular Microscope - MT6830","offer_id":58650992247109,"sku":"MT6830","price":6925.0,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1066\/1930\/6309\/files\/MT6800.jpg?v=1784748373","url":"https:\/\/auckland-scientific.co.uk\/products\/meiji-techno-mt6800-plm-pcm-combination-asbestos-microscopes","provider":"Auckland Scientific Ltd","version":"1.0","type":"link"}
