LM Scope makes very nice things, but they are quite expensive for the private individual.
There are at least two methods as alternate.
contact Tim Spauwen at Spauwen Research and Expertise. His website is
http://www.WildMicro.comHe is redoing the website so it may not be up yet. His email is
spauwe@hotmail.comHe will sell you a device specifically designed to adapt a crop frame (ie. non full frame) camera such as a Sony NEX6 to your M400
He is in the Netherlands.
There is also this item on ebay which the seller Mark Malkin is planning to make available regularly. He is someone who has been interested in M400s as long as I have and is quite expert about them and also about microscopy and macrography generally.
http://cgi.ebay.com/ws/eBayISAPI.dll?Vi ... RK:MESE:ITHe is in the USA at Cornell University.
Finally it is possible to use one lens contained in the camera that came with your M400.
The long lens that is contained in the camera can be unscrewed from the front. It can then be screwed into a Wild 0.32x adapter
Hard to find and you will be bidding against me and the above two and also several dealers. You might entice the above two to trade one of their adapters (crop frame only) to trade for your Snoot Lens (as we call it.) But I recommend keeping it.
I am going to recommend to Tim that he manufacture an adaptation which allows the snoot lens to attach to a T-2 or M42 mount.
There is also a company in the USA that called Diagnostic Instruments. They sell adaptations for more microscopes than anybody else on the whole planet. They have done so for a long time.
They have several products to do the job. You would need to get one of their M400 clamps ($450!!) and a HR or HRD series coupler.
They also have C mount couplers. The coupler depends on the the size of the sensor. The clamp adapts to the microscope and the coupler to the camera. Their catalogs are very confusing and many products are discontinued. Other products are available but not in the catalog or website. However I can help you since I know more about their products than many of their newer employees.
They are also not inexpensive. But their products are world class. They are quietly sold by many big name companies in particular Zeiss has sold a lot of Diagnostic Instruments gear without really admitting it explicitly. If you know what to look for you see their gear in other catalogs too. A little less so now that things can be made more cheaply in the far east. DI products are built in the USA in Michigan.
http://webstore.diaginc.com/category-s/3.htmI am always happy to help a new M400 owner. So is Tim Spauwen, and also, Mark Malkin. Feel free to send a private message.
Also tell the forum members here how you like your scope.
BTW, you have the 100 watt dark field base. Excellent for gemology(my interest). If you are only looking at opaque specimens, I would be happy to buy that base, and furnish an alternative.
