Carl Zeiss Jena Ergaval / Amplival - frosted filter for microscope light with handle \| ground glass	Description of this part for the microscope. This is a service part for repairing the microscope base. In the base of the Carl Zeiss Jena Ergaval / Amplival microscopes (including their variants), ... a glass frosted filter (so-called ground glass) is located in the optical light beam path. It is mounted on a steel rod ending with a handle positioned outside the microscope base - at the rear, next to the place where the illuminator is inserted. This handle is used to insert and withdraw the frosted filter from the illumination beam path. This design often leads to damage: - the glass frosted filter is mounted on the rod in such a way that the glass frequently cracks - the handle located at the rear of the microscope base very often breaks or crumbles - the metal rod often jams and as a result of attempts to move it - bends Here I present and offer this exact frosted filter with the complete movement mechanism: - glass frosted filter (ground glass) - holder for mounting the filter to the rod - all necessary screws to attach this set to the microscope base - plastic control knob for operating the ground glass Names, descriptions, terms, and search contexts under which this part is searched.

Carl Zeiss Jena Fluoval-2 / Laboval FL microscope fluorescence filter cube 450nm	Description of this part for the microscope. 450 nm fluorescence filter cube for Carl Zeiss Jena Fluoval-2 and Laboval Fluoreszenz fluorescence microscopes. This filter cube, sometimes also called a ... reflector, performs two functions: - it contains a barrier filter (emission filter) for the 450 nm wavelength - it acts as an angular mirror, reflecting the light beam from the EPI fluorescence illuminator vertically downward through the objective toward the specimen. This fluorescence filter cube fits the following EPI fluorescence microscopes: - Carl Zeiss Jena Fluoval Fluoreszenz - Carl Zeiss Jena Fluoval-2 (built on the Carl Zeiss Jena Amplival microscope platform) Important – this microscope component does not fit the first version of the Carl Zeiss Jena Fluoval microscope. The Fluoval microscope (without "2") does not use a filter cube. Instead, it has a simple permanently mounted swing-out barrier filter. The filter cube has two positions: - empty, for normal transmitted-light operation - 450 nm for reflected-light fluorescence (EPI) operation Mechanically, this filter cube is installed between the objective nosepiece and the microscope head. It slides into a dedicated slot and moves along a dovetail guide. On the Carl Zeiss Jena Laboval Fluoreszenz microscope, this slot is located in the additional upper horizontal arm of the EPI fluorescence illuminator. On the Carl Zeiss Jena Fluoval-2 microscope, the slot is located in the EPI fluorescence arm, which is an integral part of the microscope. The Fluoval-2 is based on the Carl Zeiss Jena Amplival microscope, which has a modular design. Mechanically, the Fluoval-2 is essentially an Amplival equipped with an upper EPI fluorescence arm. Sliding the cube along this dovetail guide switches between the empty position (transmitted light) and EPI fluorescence with the 450 nm filter.

1138 - Thumbnail photo showing this microscope part. Carl Zeiss Jena Jenalumar fluorescence microscope HBO 250W heat absorbing KG-filter glass - thumbnail [ 99712 ] video	SERMIK_ID number under which this microscope part is placed in the database. 99712	Carl Zeiss Jena Jenalumar fluorescence microscope HBO 250W heat absorbing KG-filter glass	The name of this microscope part. Carl Zeiss Jena Jenalumar fluorescence microscope HBO 250W heat absorbing KG-filter glass	Description of this part for the microscope. KG filter in a metal housing for absorbing heat from the fluorescent lamp of the large HBO 250W illuminator for a Carl Zeiss Jena Jenalumar microscope. ... This filter is mounted in the sheet-metal housing of the large HBO 250W fluorescence illuminator. This illuminator is part of a large mirror light beam splitter used in Carl Zeiss Jena Jenalumar microscopes. The KG filter is designed to absorb heat (infrared radiation) emitted by the high-pressure HBO mercury lamp. Please note that there is also a version of the Carl Zeiss Jena Jenalumar microscopes with a small 50W HBO illuminator. This KG filter glass was removed from a large 250W illuminator. On the used market, in microscopy forums and in microscopy groups, several names are used for this filter, all referring to the same type of filter: - KG filter / KG glass - heat filter - heat absorbing filter - heat absorption filter - heat-absorbing glass - heat absorption glass - absorption filter - IR filter - infrared blocking filter - infrared cut filter - KG3 heat absorption filter This microscope element is highly susceptible to damage. When this happens, the filter needs to be replaced, for example with the filter presented here. Here are examples of damage that can occur during use of the fluorescence illuminator and reasons why replacement of the filter may be necessary: - the KG filter may crack or become cloudy due to overheating - the filter may also chip or break as a result of mechanical damage, for example during transport - the filter may sometimes be damaged during improper maintenance High-performance heat filters such as this KG filter used with a 250W lamp are very often used by people building their own DIY projects. The housing with screw mounting makes this particularly convenient. The last photo in the gallery shows the housing of the HBO 250W illuminator (lampenhaus), with an arrow indicating which element is being described and where it is located inside the illuminator. This makes it possible to identify the element unambiguously. Names, descriptions, terms, and search contexts under which this part is searched.
