Carl Zeiss Jena Amplival - Ergaval microscope field diaphragm iris	Description of this part for the microscope. Field diaphragm (iris diaphragm) for the base of the Carl Zeiss Jena Ergaval / Amplival microscope. It allows adjustment of illumination in the Koehler system. ... This is a component of the transmitted light optical path - it is not a diaphragm for EPI reflected light.

Carl Zeiss Jena Amplival / Ergaval microscope - single blades for field diaphragm \| iris diaphragm blades	Description of this part for the microscope. Separate, individual blades of the field diaphragm (iris diaphragm) located in the microscope base (stand foot) of the Carl Zeiss Jena Ergaval / Amplival microscope. ... This diaphragm is necessary to set illumination according to the Koehler system. This element is used in a diaphragm installed in various Carl Zeiss Jena microscope models built on the Amplival stand: - Amplival - Amplival Interphako - Amplival Pol - Vertival - Peraval - Fluoval - Docuval The field diaphragm located in the microscope base is part of the transmitted light path - it is not a diaphragm for EPI (reflected) illumination. However, it is VERY LIKELY that individual blades may also fit reflected light diaphragms and other diaphragms (e.g. aperture diaphragms) in Carl Zeiss Jena microscopes and condensers. Damage to iris diaphragm blades is one of the more common failures in Carl Zeiss Jena microscopes. Most often this occurs when: - the lubricant in the diaphragm opening / closing mechanism dries out and the user tries to move it by force - a foreign object gets between the blades (e.g. a glass fragment from a chipped microscope slide) - the diaphragm is closed too quickly or opened too far In the event of an iris diaphragm failure, it is possible to: - replace the entire element (condenser or diaphragm module) - replace only the diaphragm - repair the diaphragm by replacing the damaged blades Names, descriptions, terms, and search contexts under which this part is searched.

944 - Thumbnail photo showing this microscope part. Carl Zeiss Jena Amplival microscope aperture iris diaphragm for pancratic condenser - thumbnail [ 99487 ] video	SERMIK_ID number under which this microscope part is placed in the database. 99487	Carl Zeiss Jena Amplival microscope aperture iris diaphragm for pancratic condenser	The name of this microscope part. Carl Zeiss Jena Amplival microscope aperture iris diaphragm for pancratic condenser	Description of this part for the microscope. Aperture iris diaphragm for the Carl Zeiss Jena panchromatic microscope condenser used in Amplival-class microscopes. Basic data: Manufacturer: Carl Zeiss ... Jena Version: grey version, removed from a Carl Zeiss Jena Amplival microscope Mounting method: aperture diaphragm in the form of a detachable module Centerable: yes This iris diaphragm module is mechanically mounted to the bottom of the panchromatic condenser. In Carl Zeiss Jena panchromatic condensers, the diaphragm is designed as a detachable module because it can be removed and replaced, for example, with a phase contrast module or a polarization module. Precisely because this microscope part can be detached, it is often missing from condensers available on the secondary market - over the years it simply gets lost. Interestingly, this microscope part is very often modified. When users do not have a phase contrast module or a polarization module, they frequently insert polarizing film or custom-made phase rings into the aperture diaphragm module and obtain the functionality they need through DIY modifications. This module can also solve a common problem found in Carl Zeiss Jena Amplival microscopes, namely damaged diaphragm blades in the condenser.
