LOMO microscope hunting for you

Have a problem finding shops that sell specific materials? Ask here. Are you looking for microscope parts? Do you have anything to offer for sale? Note: this is not a section for external companies to advertise their products.

LOMO microscope hunting for you

#1 Post by Dmi3n » Mon Feb 10, 2020 8:02 pm

Greetings to everyone. I live in Russia and there are many cheap LOMO microscopes available for me as I have some contacts in institutes and univesrsities who ocasionally upgrade their gear so old but still good (often they were on the shelf 99% of time) microscopes are sold dirt cheap or even thrown away. I know pretty much about LOMO microscopes and can fully service them from re-greasing to machining new parts. So I can find pretty much any microscope for you, from student Biolam to research Lyumam, service it properly if needed and ship to you for good price. Also I can find individual objectives, eyepieces, parts, anything. I can sell it via Ebay to provide guarantees. PM me if you need anything.
Scopes: CZJ NfPk w/ 45mm apo objectives, Phv phase contrast, Epi Pol illuminator, trinocular head, CZJ Epityp-2 Pol (currently dismantled for full restoration and recollimation) w/ D32 microhardness tester and photomicrography attachment.

Hi Dmi3n,

My first microscope was one of those ubiquitous BIOLAMs, which I still have and use. Recently I aquired a few more LOMO models that I'm restoring: a Metam-IQ, a Laboroscope and an Invertoscope (I'm quite fond of this last one).

I've been keeping an eye on Ebay but some parts are a bit hard to find there, so I'm going to take advantage of your kind offer to do some part hunting. Right now I'm interested in TQA 20x and 10x objectives, these are long working distance objectives for the inverted microscopes, and in a 10x QPA phase objective for the Laboroscope. If you happen to stumble upon any of those let me know! I'd be happy to by them from you through Ebay.

Other parts I'd be interested to get my hands on, eventually, are the EPI arm of a LUMAM, to upgrade the Laboroscope (since the rest of the microscope body is the same for both models), and perhaps the variant of the oblique condenser for the Laboroscope.

Besides hunting for parts I'm also looking for information about the DIC module for the Invertoscope. From the little that I've been able to grasp from bits and pieces on the Internet, it looks to me that its not real DIC but more of an oblique illumination hack, perhaps you know more about this?

Regards,
jmp

Hi jmp, unfortunately those newer microscopes are quite rare at used market because they are still used in work in laboratories. If I find anything, I'll PM you. As far as I know, there was no mass-produced LOMO DIC modules, only some prototypes.

Hi Dmi3n,

Seems I can't reply via PM (registered recently, can receive but not send PM). Any way, thanks for the info, and yes, please send me the PDF that you have for the Biolam P-1. The model sold in the US specifically mentioned DIC as an option for it. Then there's this:

This is a filter that is a perfect fit for the P-1, it has a polarizing filter and a slit beneath it but no trace of a Nomarski prism. That's why I get the impression that this filter is more for oblique lighting that anything else.

Saludos,
Jmp

Hi jmp. I have seen many P-1s for sale, but none of them had this filter. I'll upload manual at google drive soon and send you the link.

HiJmp,
for the PZO DIC system there was a slit condenser as one option. It is used in combination with a prism above the objective and gives a 3D DIC effect but more oriented that the effect that results from the use of a prism condenser.
