This is description of this part:
Microscope objective with 10x magnification for MOTIC microscopes.
Basic parameters of this objective:
Manufacturer: MOTIC
Engraving on the barrel: 10/0.25 160/0.17
Magnification: 10x
Numerical aperture N.A.: 0.25
Tube length: 160 mm
Parfocal length: 45 mm
Cover glass: according to the engraving on the barrel 0.17 mm, but with 10x objectives a cover glass is in practice not required - the objective works both with and without one
Immersion: no (this is a dry objective)
Thread: RMS
I have personally tested this objective with the following microscopes:
- MOTIC B1
- MOTIC SFC-100
- PZO Studar
- Carl Zeiss Jena Ergaval
- Olympus CH
This MOTIC microscope objective will work well in a microscope from any manufacturer, provided it has an RMS thread, optics corrected for a 160 mm tube length and accepts objectives with a 45 mm parfocal length. As for the parfocal length: in the vast majority of cases (almost always) objectives with a 45 mm parfocal length can also be fitted to microscopes originally sold with so-called short barrel objectives, that is with a 33 mm or 37 mm parfocal length. In such a case it is more convenient not to mix the objectives and to have them all of the same length - but that is only a matter of convenience, not a requirement. In the compatibility section I do not list microscopes from other manufacturers, because that list would need several hundred entries.
This also works the other way round: in the MOTIC B1 and MOTIC SFC-100 microscopes you can use any objective with an RMS thread, corrected for a 160 mm tube length and with a 45 mm parfocal length - from any manufacturer. These can be unbranded objectives, PZO or Carl Zeiss Jena objectives - but the objective offered here will please those who own a MOTIC microscope and want to complete it with original parts.
What is this part needed for?
- if you own a compatible MOTIC microscope, are missing the 10x objective for it - and want to complete it with original parts
- if you want to use this objective in any other compatible microscope
