Carl Zeiss Jena Nf / NU microscope oblique illumination sliding iris diaphragm - thumbnail [ 99575 ] video	SERMIK_ID number under which this microscope part is placed in the database. 99575	Carl Zeiss Jena Nf / NU microscope oblique illumination sliding iris diaphragm	The name of this microscope part. Carl Zeiss Jena Nf / NU microscope oblique illumination sliding iris diaphragm	Description of this part for the microscope. Iris diaphragm module for Carl Zeiss Jena Nf, NU and NU-2 microscopes. In the following microscopes: - Carl Zeiss Jena Nf - Carl Zeiss Jena NU and NU- ... 2 this module serves as the aperture diaphragm. The field diaphragm is built into the illumination path inside the microscope base. At the same time, it provides a holder for 32 mm round filters. The video available in the gallery also demonstrates how a filter is inserted into this holder. The sliding iris diaphragm mounted beneath the microscope condenser allows oblique illumination to be set, producing a three-dimensional image with enhanced contrast of transparent specimens (such as unstained cells). The resulting image is similar to differential interference contrast (DIC). This component is known under various names, including: - decenterable iris diaphragm - decentering aperture diaphragm - off-axis iris diaphragm - eccentric iris diaphragm - sliding iris diaphragm - sliding iris - oblique illumination condenser - condenser with sliding iris - oblique illumination module - oblique illumination diaphragm - offset iris - Poor Man's DIC device Note — this diaphragm DOES NOT FIT the Carl Zeiss Jena Lumipan microscope, even though it appears very similar at first glance. Because this module is removable, it is missing from a large proportion of microscopes available on the second-hand market. During decades of use, these diaphragm modules were frequently lost. In addition, they are often damaged and need replacement. The most common failures include: - the protective glass covering the diaphragm becomes scratched or broken - the diaphragm blades become bent or broken - the screw used to decenter the diaphragm bends or breaks - the return spring responsible for restoring the diaphragm to its centred position becomes damaged or is missing Replacing the damaged assembly with the diaphragm module offered here solves these problems.
