Objective EC "Plan-Neofluar" 1.0x/0.025 M27

Item no.: 420300-9900-000
Description

Objective EC Plan-Neofluar 1x/0.025 M27 (FWD=3.0mm)

Full Description

This objective is used as an overview objective for Histology.

It permits viewing of an object field with a diameter of up to 25 mm. This means that a standard 26x76 mm slide can be entirely examined with a single move in the x-direction. Therefore an adequate field illumination is required. The only condenser which illuminate the 25 mm diameter object field (not possible anyway without a condenser) is the achromatic aplanatic universal condenser 0.9 used in the brightfield position and with swung-out front lens.

On account of its low aperture, this transmitted-light objective can be used with cover slips of any thickness or without any cover slip at all.

EC Plan-Neofluar

The Enhanced Contrast “Plan-Neofluar” universal objectives with consequentliy minimized stray light: with a visible increase in contrast important for all contrast methods: brightfield, darkfield, phase contrast, DIC, fluorescence, Pol. They feature high resolving power and brilliant, rich-contrast, completely flat images for observation and documentation. Their high transmission of wavelengths from the near UV range (>40% starting at 340nm) and the use of glass types of low autofluorescence makes these objectives ideal for epi-fluorescence microscopy. Further special-purpose members of the family are EC “Epiplan-Neofluar” objectives for reflected-light work, the EC “Plan-Neofluar” Antiflex objective for reflection contrast, and EC “Plan-Neofluar” Pol objectives for the requirements of polarizing microscopy.
