I posted this to micoscope@groups.io but hope to widen the search. Greetings: I found another rabbithole to ponder. From D. A Johansen Plant Microtechnique 1940 page 122-123 he states that the AO 860 sledge microtome is to be used for harder specimens but then goes on to state that the AO 820 had a ...

I have a 402a in use on my primary OP. I acquired another OP that needs some work and it has the phase ccntrast 6 position condenser with 0.90 achromat tilt lens it has a unmarked annuli access plate plate but a Leitz Wetzlar labeled body that has a Dxxxxx marked below the company name. The issue is...

Kirby: The issue was misalignment of the oculars. Gregg on the io group pointed out that the 4 screws holding the ocular tube could be loosened to attain coincident image. DId that and the image coincided He also brought up a good way for focus block alignment using a 4x objective. bring objective d...

Followed the "eyeball it" strategy on aligning the focus block. maintained shim location and used the field iris stopped down to confirm alignment, Have been able to take images in brightfield, phase contrast, dark field Not bad for parts Leitz... Last item to address is Trinocular alignment due to ...

Question has come up about Leitz horizontal nosepiece dovetail dimensions Orthoplan/Metalloplan 49.5mm widest part of dovetail. Metallux ? Additionally, any information as to how much system mechanical compatibility between the Metallux series and the *plan series? What was the Metallux market as op...

agreed
looking to get a machinist to fab up the threaded alignment plate...that would take care of theta... still thinking about concentricity alignment..

I ended that last post without asking the question. Considering the chemistry age of the Lietz lubricant with it's tendency for polymerization was the heat cycle of 240-250 F for 30 minutes aggregate of any use? Or given the state of the lubricant that it is unaffected by heat? Am interested in know...

Kirby: thanks for the comments Yes... I would rather not relive that moment. In hindsight I should have tripled the heat and lubrication cycles but that is in the past now... As for the condition of the plastic gear it will have to wait until the focus block is removed to inspect and lubricate the s...

In December I ordered the Plusgas dismantling lubricant from across the pond... it arrived last week and Monday I decided to see if the coarse adjustment was frozen or something more dramatic had occurred. Going somewhat blind as to the best flow I applied the lubricant to to exposed pin bearings ex...

small world... Arthur (Roseoptics) tuned up my AO10 ten years ago and sold me a AO Cycloptic binocular dissecting scope around the same time! Last time I was in touch with him was in the mid teens! Good guy.. I need to bone up on the Kohler illumination. I use Kohler to insure proper illumination of...

Apologies for the slow response, I can only thank Precision Instruments (name unknown) for your time and effort sharing your Leitz focus block notes and for your cautious warning that you offer. I thank Kirby for his advise but it doesn't seem to be more direct and have less complexity as the specif...

Many thanks for the comments. You offered sage advice and warnings. I am not overly enthusiastic about that disassembly process but I am thinking this would be a winter project that might result in gaining a moderately useable scope. Some more questions. 1. I sm using Naptha (Ronsonol) as the solven...

Greetings: Last spring I purchased a Leitz Orthoplan (non functional) from Ebay for spare parts (602A Phase condenser/quintuple turret/ 1x dovetail objective holder/6X GW eyepieces/ etc..etc..) the 1x was stuck in the frame due to the set screw sheared broken off. I was able to drill and use a LH th...

Ross: Since the one head is mounted on the illumination ring vertically and the trinocular head is mounted horizontally on the ring allowing 360 degrees rotation there is no issue unless the parties wish to bump heads... The illumination ring with the illuminated positional arrow is what prevents d-...
