# Part name: Carl Zeiss Jena PM XVI T-coated Stereo Microscope Objective 2.5x | SM-16 paired objective with anti-reflective coating # Original page URL: https://www.microscopeparts.eu/part/carl-zeiss-jena-pm-xvi-t-coated-stereo-microscope-objective-2-5x-sm-16-paired-objective-with-anti-reflective-91036 # Part manufacturer: Carl Zeiss Jena # Full manufacturer name: VEB Carl Zeiss Jena DDR (former East Germany) # Other names of this manufacturer: - ausJena - aus Jena These are names commonly used to refer to this manufacturer of microscopes and microscope parts, even if they are not official. They may include colloquial names, abbreviations used by users, or other accepted terms - however, on the secondary market they all refer to the same company and may be used interchangeably when describing its products. # Belongs to category: Objective # Description and specifications: Objective with 2.5x magnification and T anti-reflective coating for the Carl Zeiss Jena PM XVI stereo microscope. Basic information: Objective type: for stereo microscopes, a so-called "objective pair" Magnification: 2.5x Anti-reflective coating: yes, this is an objective carrying the red letter "T", i.e. T-coated On the black plastic housing the magnification is written as "2,5" - unlike the older versions of such objectives (made for the Stereomikroskop XII model), where the format used was "2 1/2" (see here: https://www.microscopeparts.eu/part/91035) In stereo microscopes built on the Greenough principle, what is called "the microscope objective" is in fact a pair (two pieces) of objectives set at a specific angle to each other. This is exactly why the housings of older examples of such objectives (more precisely: the common housing covering the pair of objectives) carried two serial numbers. Each of these objectives simply had its own individual serial number. Such a case can be seen on this 1.25x objective: https://www.microscopeparts.eu/part/00654. This technical design has a very interesting consequence - each single objective, once taken out of the housing, becomes an interesting choice for anyone working in macro photography, all the more so because these are usually low-magnification objectives, which are exactly what macro photography looks for. Since the 1930s Carl Zeiss Jena has produced many models and variants of stereo microscopes, and this objective will fit the vast majority of them, because the way they are mounted is the same throughout. Several names are in use on the market for the stereo microscope this objective comes from: - Carl Zeiss Jena Stereomikroskop XVI - Carl Zeiss Jena Präpariermikroskop XVI - Carl Zeiss Jena Stereomikroskop PM XVI - Carl Zeiss Jena SM XVI - Carl Zeiss Jena PM XVI Sometimes, to avoid Roman numerals, you also come across the spellings "SM-16" and "PM-16". Interestingly, in the instruction manual from 1954 available online (https://www.microscopemuseum.eu/catalogues/Carl_Zeiss_1954_Stereomikroskop_PM_XVI.pdf), the header on page 3 reads "Stereomikroskop PH XVI". I do not know whether this is an OCR error or an original misprint, but it means that this (incorrect) name may be in circulation as well - and all of the names listed above refer to one and the same microscope. # Examples of use - if you own such a microscope without objectives and therefore need at least one objective - if you need an objective to replace a damaged one, or if your current objective is in very poor condition - if you have a microscope with objectives of other magnifications and want to have them all - if you already have a 2.5x objective but without the anti-reflective coating and want one that has it # Removed from microscope: Carl Zeiss Jena PM XVI # Also compatible with the following microscopes: - Carl Zeiss Jena PM XVI - Carl Zeiss Jena Stereomikroskop Stativ XII # Names, descriptions, terms, and search contexts under which this part is searched. - Carl Zeiss Jena PM XVI microscope repair parts - Carl Zeiss Jena SM XVI Objektiv 2.5x - Carl Zeiss Jena PM XVI objective 2.5x - Carl Zeiss Jena Präpariermikroskop XVI Objektivpaar - Carl Zeiss Jena SM-16 paired objective 2.5x - Carl Zeiss Jena PM-16 Objektivpaar 2 1/2 - Carl Zeiss Jena PH XVI Objektiv - Stereomikroskop XVI Objektiv T-vergütet - Zeiss Jena stereo microscope objective pair T-coated - Greenough objective pair on dovetail slider - Zeiss Jena Stereomikroskop Objektiv gesprungen - Zeiss Jena stereo microscope objective cracked lens - Objektiv für Zeiss Jena Stereomikroskop ersetzen - replacement objective Carl Zeiss Jena stereo microscope - Zeiss Jena Stereomikroskop aufarbeiten Objektiv fehlt - single objective from stereo microscope for macro photography - objektiv stereomikroskop Carl Zeiss Jena - objetivo 2.5x microscopio estereoscópico Carl Zeiss Jena - par de objetivos microscopio estéreo Carl Zeiss Jena PM XVI - obiettivo 2.5x stereomicroscopio Carl Zeiss Jena - coppia obiettivi stereomicroscopio Carl Zeiss Jena SM XVI - obiektyw 2.5x do mikroskopu stereoskopowego Carl Zeiss Jena - Carl Zeiss Jena buy spare parts # Related URLs: - Markdown po polsku: https://www.serwismikroskopowy.pl/part/91036.md - Markdown auf Deutsch: https://www.mikroskopteile.de/part/91036.md - Gallery of all photos of this part: https://www.microscopeparts.eu/gallery/91036-carl-zeiss-jena-pm-xvi-t-coated-stereo-microscope-objective-2-5x-sm-16-paired-objective-with-anti-reflective - Media manifest of this part (photos + videos, for AI/RAG): https://www.microscopeparts.eu/part/91036.media.md - Representative photo: https://www.microscopeparts.eu/photo/carl-zeiss-jena-pm-xvi-t-coated-stereo-microscope-objective-2-5x-sm-16-paired-objective-with-anti-reflective-91036-2 - Representative video: https://www.microscopeparts.eu/play/91036-1 - Other parts from category Objective: https://www.microscopeparts.eu/objective - More Objective removed from microscope Carl Zeiss Jena PM XVI: https://www.microscopeparts.eu/objective/from/carl-zeiss-jena/pm-xvi - More Objective compatible with microscope Carl Zeiss Jena PM XVI: https://www.microscopeparts.eu/objective/for/carl-zeiss-jena/pm-xvi - More Objective removed from microscopes Carl Zeiss Jena: https://www.microscopeparts.eu/objective/from/carl-zeiss-jena - More Objective compatible with microscopes Carl Zeiss Jena: https://www.microscopeparts.eu/objective/for/carl-zeiss-jena # Important information: Database Description: Technical microscope parts database based on years of practical service experience.
