Objective W Plan-Apochromat 20x/1.0 Corr DIC M27 75mm

Item no.: 421452-9700-000
Description

Objective W Plan-Apochromat 20x/1.0 Corr DIC M27 75mm Parfocal length 75mm (FWD=2.4mm), UV-VIS-IR Correction collar for differences in refractive index nD from -0.002 to 0.025. Apochromatical correction of longitudinal colour aberration includes the wavelength 405 nm.

Full Description

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.

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.
