These objectives have been specifically designed for Life Cell Imaging techniques and are designed for the temperature interval between 23° and 37°C. The 25x/0.8 can be used with the immersion mediums water, glycerine and oil, while the 63x/1.3 can be used with water and glycerine. A single correction collar permits simple and convenient compensation for spherical aberration caused, for example, by different cover slip thicknesses, temperature drift or immersion media with a different refractive index, adjustable between water and glycerine. For the examination of living objects, water is particularly suitable as immersion medium. Furthermore, cleaning is extremely easy. For critical fluorescence examinations, cleaned glycerol is the ideal immersion medium, as it has very low autofluorescence. Therefore, glycerol and water should be preferred for the microscopy of living objects, since these are found in a medium with a similar refractive index. The "Refractive Index Mismatch" indicates the deviation of the actually available refractive index from the one that the objective has been calculated for. This deviation too can be compensated for by means of the correction collar. Used with inverted microscopes, multi-immersion objectives are ideal for the limited compensation of non-standard glass bottom thicknesses (D ≠ 0,17) or the popular use of water as immersion medium with a slightly lower numerical aperture than oil-immersion objectives.
Special emphasis has been placed on good accessibility of the optical axis with micromanipulators.
