Carl Zeiss Jena Ergaval / Amplival microscope coarse focus knobs

The name of this microscope part.

Carl Zeiss Jena Ergaval / Amplival microscope coarse focus knobs

Description of this part for the microscope.

Microscope knob for coarse movement (macro focus).

Such knobs are used in the following microscopes:
- Carl Zeiss Jena Ergaval
- Carl Zeiss Jena Amplival ...

(and its variants: Fluoval, Epival, Vertival)
- Carl Zeiss Jena Metaval
- Carl Zeiss Jena Docuval

Both the left and the right knob are identical, but when installing be careful about the screw length, as they may differ).

VERY IMPORTANT: although the right and left knobs are identical - different screws are used to attach them.

Lengths of screws used to attach the knobs in Carl Zeiss Jena Ergaval and Amplival microscopes:
- left fine adjustment knob (micro): 1 pc. screw 12 mm
- left coarse adjustment knob (macro): 3 pcs. screws 8 mm
- right fine adjustment knob (micro): 1 pc. screw 16 mm
- right coarse adjustment knob (macro): 3 pcs. screws 12 mm

Over the years these plastic knobs are often damaged:
- sometimes they crack due to impact or improper transport securing
- often they are partially melted by a soldering iron, light bulb or even a cigarette
- sometimes they are damaged during attempts to remove them

Carl Zeiss Jena Ergaval / Amplival microscope coarse and fine focus shaft | repair spare part

The name of this microscope part.

Carl Zeiss Jena Ergaval / Amplival microscope coarse and fine focus shaft | repair spare part

Description of this part for the microscope.

Service microscope part (repair element) for Carl Zeiss Jena Ergaval / Amplival microscopes and related models.

This is the coarse and fine focus shaft, ...

meaning the shaft with focusing knobs mounted on both ends on the sides of the microscope. Part of this shaft contains a toothed rack, or more precisely speaking, it is a toothed shaft. In the item shown and offered here, the fine focus knob (micro focus) is mounted on the left end of the shaft. Please note that the left and right knobs are identical - however, screws of different lengths are used to attach them: the left knob is attached with a 12 mm screw, while the right knob uses a 16 mm screw. Detailed information about the screws used to attach the coarse and fine focus knobs can be found here: https://www.facebook.com/MikroskopyPZO/posts/pfbid0x2tFPHAEqjn4B7BRsvm2vAt9yyuuSM836QS6K4951GqeUFpU2FJH8YXfFFxbz3cPl

Such focus shafts are used in the following microscopes:
- Carl Zeiss Jena Ergaval
- Carl Zeiss Jena Amplival (and its variants: Fluoval, Epival, Vertival, Interphako)
- Carl Zeiss Jena Metaval
- Carl Zeiss Jena Docuval

This coarse and fine focus shaft may help solve the following problems in Carl Zeiss Jena Ergaval / Amplival microscopes and related models:
- if the shaft became bent, causing a noticeable jump while rotating it (a very common failure)
- if the screw holding the fine focus knob broke off or snapped, leaving part of the screw inside the shaft
- if the left fine focus knob is missing or damaged
- if the thread on the right or left end of the shaft, where the fine focus knobs are attached, is damaged
- if the toothed rack on the shaft (because such a shaft is effectively a toothed shaft) becomes damaged

Carl Zeiss Jena Ergaval / Amplival microscope coarse and fine focus lock washer

Description of this part for the microscope.

Multi-tooth locking washer (alternative name: bendable tab washer) - a service component of the coarse focus and fine focus mechanism responsible for vertical movement ...

in the microscope.

As far as I know, the same mechanism is used in the following Carl Zeiss Jena microscopes:
- Ergaval
- Amplival
- Fluoval
- Vertival
- Epival
- Docuval
- Metaval
- Peraval

This component is installed onto the shaft by sliding the internal tab into the keyway groove on the shaft. After tightening the round slotted nut, a locking mechanism is created that prevents the nut from loosening on its own due to vibration.

Carl Zeiss Jena Ergaval / Amplival microscope coarse and fine focus split taper-lock bushing

The name of this microscope part.

Carl Zeiss Jena Ergaval / Amplival microscope coarse and fine focus split taper-lock bushing

Description of this part for the microscope.

Split taper-lock bushing (alternative name: expansion and clamping ring) - a service component of the coarse focus and fine focus mechanism responsible for vertical ...

movement in the microscope.

As far as I know, the same mechanism is used in the following Carl Zeiss Jena microscopes:
- Ergaval
- Amplival
- Fluoval
- Vertival
- Epival
- Docuval
- Metaval
- Peraval

This component acts as a resistance regulator and functions as a friction brake. Tightening the outer element compresses the tapered section of the bushing, causing the slotted bushing to contract at the slit. This increases friction on the shaft and makes the entire mechanism move with greater resistance.

Note - in some descriptions available on the Internet, this component is referred to as a "piece of wood".
