AUS JENA (HBO LAMP SUBSTITUTE) 750W 120V HALOGEN PHOTO OPTIC FOR MODIFICATION
Note:  This is not an approved (by any one who matters) modification.  Please read the whole description.
This modification is not for every one.  What I am selling is one 750W 120V halogen photo optic lamp.  New and in it's original packaging.
Years ago I had an extra aus Jena HBO (mercury) lamp house.  I really didn't like using the HBO set up I had so I started playing around with my extra lamp house.   I tried many bulbs for quite some time and finally stumbled onto this particular configuration bulb.  One that had easy to wire in leads as well as just the right diameter tube shaped base.
I wired it in with wire nuts (easy) but the best part was the mercury lamp house clamp just fit this bulb.  All the lamp adjustment still worked and I could slide it up and down in this clamp for easy centering.  I was able to achieve proper Kohler illumination.  This is shown by the focused filament on a piece of paper laying under the condenser shown in a photo.
I added a high wattage rheostat (dimmer switch) and a heat filter at the beginning of the optic train in the scope.  I have used this set up for ten years and ran it a lot as I was writing the monthly "Micro Visions" articles for Meteorite Times.  It took me 6 years to burn out my first bulb.  I generally don't turn the dimmer all the way up because it is just not necessary unless I am trying to capture a great photo in rather dense material.  This helps avoid excess heat as well as makes the bulbs last a very long time.
What having all this extra light has done for me is allow me to capture beautiful saturated colors even in very high magnifications.  For example the first two micrographs (in the set of three) were taken of a meteorite thin section NWA 969 LL7 at 160X and the third image is the same material at 400X.
Using this set up I won the Zeiss Photomicrograph contest one year and got one of my Lunar Meteorite images in their company calendar.
All the ample light makes things easy.  The last photo in this listing is a meteorite thin section Al Hugf 007 L4 taken at a magnification of 160X using my point and shoot camera held up to the eyepiece (zoomed in just a little) with no stabilization.  Just held up there and click!  I snapped it for this listing.
I took my lamp house off of my scope, an aus Jena Fluoval, to show what it looks like and how it attaches.  You can see that after 10 years of use, the lamp house shows no sign of heat damage.  (They are designed for a lot of heat with the mercury burners.)
Some things to consider:  120V into your microscope, Use a quality grounded cord and don't cheat it with a ground plug adapter.  The lamp house must have a proper ground for safety.
This only works with the large HBO aus Jena lamp houses.  It is to large for the 12V 100W lamp houses and there is no bulb clamp!
Heat is an issue to your scope.  You must put in a heat filter (Glass lens that you may need to get creative to fit) at the entrance to your microscope.  You could crack a lens or a mirror from heat if you do not.  Personally, I found a Schott filter on eBay that fits in my filter carrier.   Not many Jena scopes have a filter carrier like a Fluoval, so you would need to put one (Glass heat filter) at the point your lamp house connects to your microscope.  (It sounds worse than it really is, if you have a HBO burner, then your set up is already made for a lot of heat and likely has a heat filter, don't mount this set up on your unprotected Amplival just like you wouldn't put your HBO set up ((with out protection)) on it either.)
(I set up a standard Amplival for a friend and we took a generic heat filter to a tile wet saw and used the side of the blade to grind down the lens until it just fit in the back of his scope in front of the lamp.)
I list this Halogen bulb as an aus Jena HBO fix because so many of the Jena HBO set ups (That I know of) are non functional due to hard to find and expensive bulbs as well as heavy power supplies that are not easy to get.
Not to mention the harmful (To your eyes) wave lengths the HBO lamps put out.  They should be used with proper filters.  Having used and photographed with both, the only thing I would use the original HBO lamp for is maybe florescence work.
I also use an aus Jena XBO (Xenon) set up and the colors produced with the XBO and the Photo Optic Halogen are similar.  HBO (Mercury) has dramatic color change effects.  So what I am saying is I think that, once it is set up, you will like using this halogen more than your HBO.  Not to mention the cost difference in bulb replacement.
Meteorites under the microscope is my hobby.  Check out my old (I no longer write these) Meteorite Times articles called Micro Visions. Here is a link to a back issue list (with live links) of my articles. There is some beautiful art in those micrographs and some useful information (I hope!).

Also, my son is setting up a Gallery and art sales site of my micrographs. Please check it out

I am currently setting up my meteorite micrograph gallery within this site.  My old gallery has been down for some time, keep checking it out as it is an ongoing project.
The exact part number of the bulb is 750Q/JKT/LEADS/AM-ULS 750W 120V and it's NAED # is 54860.  The list price on this bulb is much higher than my Buy it now price.
Only the bulb is included, no other microscopes or parts!
