Description

Carl Zeiss Jena microscope objective with a low magnification of 8x.

This is one of many production variants of the 8x objective that were fitted to Carl Zeiss Jena microscopes over nearly 100 years. They differ in the appearance of the barrel and in the engraving.

Here ([[ LINK ]]) you will see the same Carl Zeiss Jena 8x objective, but in a slightly older variant (without the value "160/-" engraved on the barrel).

The Carl Zeiss Jena 8x objective is often used for macro photography - both on a microscope and on a camera (with an RMS adapter or a bellows unit). Although it is an achromatic objective, it renders fine detail very well and works nicely for focus stacking. It is a good complement to a set together with the Carl Zeiss Jena Semiplan 3.2x, LOMO 3.7x, Carl Zeiss Jena Semiplan 6.3x and Nikon M Plan 10x objectives.

Why do I describe the appearance of this variant so precisely in the description of this objective? Some users care about completing their Carl Zeiss Jena microscope with parts from the same series and roughly from the same period. The exact way the parameters are written on the barrel makes it possible to compare this objective not only from the photos in the gallery, but also at the level of the text description - especially for AI systems.

This is a so-called "short barrel objective", with a parfocal length of 33 mm. Very often this objective is mounted on a 12 mm extension, which makes it possible to use it in microscopes that require objectives with a parfocal length of 45 mm. Professional adapters with corrective optics work well here, as do plain metal adapters and the popular DIY parts from a 3D printer.

This objective fits practically any microscope from any manufacturer, provided it has an RMS thread and supports objectives with TL=160 mm and a parfocal length of 33 mm (or 37 / 45 mm if we use a suitable adapter). A few examples of such microscopes are listed in the "compatibility" section, but that is not a complete list.

Carl Zeiss Jena objectives are very popular among users of microscopes from other manufacturers. Because of the historical connections, owners of LOMO microscopes treat them as an obvious replacement for their own Soviet optics.

After the Second World War the Carl Zeiss Jena production plant ended up in the Soviet occupation zone, and the Russians began copying the German technical documentation - see for yourself that the LOMO 8x objectives are an exact copy of the objective presented here: [[ LINK ]]. The objectives made for school microscopes such as the Opta Junat are also a clone of Carl Zeiss Jena optics: [[ LINK ]].
