    W Plan-Apochromat

    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.
