Description of this part for the microscope.

08 160/-
Color correction: Planachromat
Numerical aperture: 0.08
Tube length: 160 mm
Focal length: 45 mm
Cover glass: no
Immersion: no
Thread: RMS

This lens provides an excellent, wide image, and because it doesn't require a cover glass, it's often used for macro photography and stacking.

Important - this lens is not suitable for taking photos using the "direct-projection" technique, as it requires plan-compensation optics.

A microscope objective with such low magnification is used, among others, in the following fields:
- tissue overview examination in pathomorphology
- observation of insects
- observation of minerals
- observation of inclusions in amber
- handwriting analysis
- observation of micromollusks
- and many others

Length: 45 mm
Cover Glass: yes, 0,17 mm
Immersion: no
Thread: RMS
Info: Ph = phase contrast

It can be used with any microscope from any manufacturer, along with a compatible phase contrast condenser. The microscope must be compatible, meaning it supports RMS objectives, TL = 160 mm, FL = 45 mm.

03
Magnification: 32x
Correction: achromat
Numerical aperture: 0.4
Tube length: 160 mm
Focal length: 45 mm
Cover glass: yes, 1 mm (!)
Immersion: no
Thread: RMS
Ph1: phase contrast
LD: "long distance" meaning long working distance

Note: this is an objective for an inverted microscope, therefore it is corrected for observation through a 1.0 mm cover glass

It can be used with any inverted microscope from any manufacturer together with a compatible phase contrast condenser (or slider with phase rings). Of course the microscope must be compatible, i.e. support RMS objectives, TL=160 mm, FL=45 mm.

It can very likely also be used with other inverted Zeiss microscopes (e.g. Axiovert 25).

06
Magnification: 20x
Correction: achromat
Numerical aperture: 0.25
Tube length: 160 mm
Focal length: 45 mm
Cover glass: yes, 2 mm (!)
Immersion: no
Thread: RMS
Ph1: phase contrast
LD: "long distance" meaning long working distance

Note: this is an objective for an inverted microscope, therefore it is corrected for observation through a 2.0 mm cover glass

It can be used with any inverted microscope from any manufacturer together with a compatible phase contrast condenser (or slider with phase rings). Of course the microscope must be compatible, i.e. support RMS objectives, TL=160 mm, FL=45 mm.

It can very likely also be used with other inverted Zeiss microscopes (e.g. Axiovert 25).

9904
Magnification: 10x
Correction: achromat
Numerical aperture: 0.22
Tube length: 160 mm
Focal length: 45 mm
Cover glass: indifferent
Immersion: no
Thread: RMS
Ph1: phase contrast

This specific unit was used in an inverted Zeiss ID 02 microscope, but I have also seen this objective model in Zeiss KF-2 ICS and Zeiss Axiostar microscopes.

Objectives with such low magnification (here 10x) can be used without a cover glass, with a cover glass, or for observation through thicker glass (e.g. through a Petri dish), therefore they can be used both in upright and inverted microscopes.

It can be used with any microscope from any manufacturer together with a compatible phase contrast condenser (or slider with phase rings). Of course the microscope must be compatible, i.e. support RMS objectives, TL=160 mm, FL=45 mm.

This particular specimen was used in a Zeiss KM microscope, but I have also seen this objective model in Zeiss KF-2 ICS and Zeiss Axiostar microscopes. It fits many microscope models from this manufacturer; some examples are listed in the "compatibility" section.

It can be used with any microscope from any manufacturer together with a suitable phase-contrast condenser (or a phase-ring slider). Of course, the microscope must be compatible, i.e. support RMS objectives, TL=160 mm and FL=45 mm.

of view number: 12
Mounting diameter: 23.2 mm
Designation: PK = plan compensating - recommended for work with planachromatic objectives, but they also work without any trouble with achromats or apochromats

Because of their very high quality they are often used on microscopes from other manufacturers as well, especially when Carl Zeiss Jena Planachromat objectives are mounted in them. The "compatibility" section lists a long series of microscopes these eyepieces fit - but that list is definitely not complete.

Important: these eyepieces work both on microscopes with a finite tube length (160 mm, for example) and on microscopes with infinity optics. That means you can use them on the Carl Zeiss Jena Amplival microscope just as well as on the Carl Zeiss Jena NU-2 microscope.

A note - eyepieces with such a strong magnification are in my opinion better suited to a quick look than to permanent work. I write "in my opinion" on purpose, because this comes from using them and not from the manufacturer's description.
A 16x eyepiece magnification should be treated as a zoom that brings out no additional detail (the resolution is not increased). This matters for example with heads that have their own extra magnification (such as Carl Zeiss Jena heads with a built-in 1.5x or 1.6x factor) - working with a 100x oil immersion objective you then theoretically get 100*1.5*16 = 2400x, while physics does not allow light from the visible range to be usefully magnified for the human eye beyond roughly 1250x - so this is what is called empty magnification.

Germany
Designation: Ph2 F40/0,65 160/0,17
Manufacturer catalogue number: 46 07 06
Magnification: 40x
Correction: Semi-planachromatic
Numerical aperture N.A.: 0.65
Tube length: 160 mm
Parfocal length: 45 mm
Cover glass: yes, 0.17 mm thick
Immersion: no (a so-called dry objective)
Thread: RMS
Phase contrast: yes, the objective has an internal phase ring matching the Ph2 position in the condenser
Specimen protection: yes, the objective has a spring-loaded mechanism that protects the slide from being crushed

The letter "F" at the beginning of the objective model name (F 40 / 0.65) means that this is a semi-planachromatic objective, i.e. flatter than an achromat but less flat than a planachromat. "F" does not mean that the objective is intended for work with fluorescence light.

This objective fits practically any microscope from any manufacturer, provided it has an RMS thread and accepts 160 mm tube length objectives with a parfocal length of 33, 37 or 45 mm. A few example microscopes are listed in the "compatibility" section, but that list is not complete.
