Due to its large parfocal length this objective can be used with the microscopes "Axio Examiner.D1" and "Axio Examiner.Z1" only .
The apochromatical correction of longitudinal colour aberration includes the wavelength 405 nm.
This objective is designed for dipping into physiologic salt solution. It can be dipped into the agent up to 7 mm deep, without liquid ending up inside the objective.
The correction collar is used to adjust small deviation of refractive indes in the range of nD from 1.33 to 1.36.
Unfortunately there is no suitable DIC slider for this objective available.

As an addition to the water "Achroplan" objectives, the water "Plan-Apochromat" objectives have also become available. They are apochromatically corrected from VIS to IR and designed for use without cover slip. Compared with the water "Achroplan" 63x/0.9, the new water "Plan-Apochromat" 63x/1.0 yields 50-100% more light. Between 450 nm and 1000 nm, the typical transmission values of the water "Plan-Apochromat" are higher than 80%, and higher than 50% at 365 nm. The objectives feature a slim front with a 20 mm diameter and a 36° access angle to the object plane. The front consists of plastic material that was originally developed with the properties required for food technology. Therefore, these objectives are ideal for 2-photon microscopy, electrophysiology and patch clamp applications.
