The immersion medium Immersol W with a refractive index ofne = 1.33 exactly matches the C-Apochromat and LCI Plan-Neofluar multiimmersion range of objectives for demandingapplications. While offering an ultimate solution for the effectivereduction of spherical aberrations, it still maintains thephysical advantages of immersion oils regarding evaporationand run-off behavior. Chromatic properties and temperaturestability are nearly perfect, and handling even in invertedconfigurations is as easy as you ever wanted it to be. To additionallyreduce spherical aberrations, ZEISS now offers highperformance coverslips of the 1 ½ H type, which are moreexact and vary much less in thickness than normal coverslipsfound on the market.In case an extremely fine Z-focus capacity is required withoutmoving the specimen, the ZEISS piezo focus attachment, especiallyfor physiological applications, adds ultrafine objectivefocusing to every microscope stand
