MAGUS DF4 dark látóterű kondenzor NА 1.3–1.26 oil

Dark visual condensor can be observed with dark vision. Dark visionary techniques can be used to take an image of non -painted and translucent patterns that do not swallow light and are not visible in a light field.

The dark field of vision condenser should be used with a lesser nominal aperture lens. The oil condensor has a compartment opening 1.3-1.26, so the condensor operates with 20x and larger enlarged lenses.

For this condensor, it is mandatory to put an immersion oil between the condensor lens and the slide, whether it uses dry or immersion lenses. If there is no immersion oil on the condensor lens, the rays of light cannot get to the sample.

The dark vision condensor is located in the maintenance instead of the Abbe condensor. There are two centering screws in the condensation that can properly adjust the opaque end -locking element in the optical route.

If you want to get a contrasting image of the sample using the dark field of view, we recommend using a 0.17 mm thick cover plate and 1-1.2 mm thick slide.
