Dear List,

I am looking for  a simple and most importantly stable inverted microscope design/layout for fluorescence microscopy and single particle tracking. It should consist of readily available "Lego bricks" (e.g. Thorlabs parts) and be versatile so that additional components can be added later. Thorlabs seems to prefer a design in which the objective is mounted on a damped post as in their optical tweezers setup (http://www.thorlabs.com/NewGroupPage9.cfm?ObjectGroup_ID=3959) , but I am not sure if this is the most stable layout.

Thank you!

Jens

I've built a number of Thorlabs systems 'on a stick' and I find the biggest
issue is the table or platform the whole system sits on. The post won't
cantilever too bad if it is on a stable base, but it will aggravate any
instabilities if you have a 'noisy' tabletop. I have a half-meter high
system on posts like this that is quite stable (CARS system), but it is on
a 45cm thick optical table which is floated. On a smaller scale, I have a
widefield system on a 10cm thick top that is 25cm tall that is fairly
sturdy with just neoprene damping feet under the breadboard. What sort of
bench/table do you have? Then I could suggest more accordingly.  If you are
building inverted a simple solution is to use a very short post or optical
rail (XT66 or XT95) or a heavy tapped block like the TS240 Tombstone:

Jens,

Have you seen the ASI Rapid Automated Modular Microscope:

http://asiimaging.com/products/video-microscopes-test-stands-complete-system-solutions/rapid-automated-modular-microscope-ramm-system/

Definitely a lego-like system as different components can be bolted to it and it can be easily customized. Not sure if it has been successfully used for particle tracking, but we have used it for localization microscopy in the past, and it is an integral part of Hari Shroff's DiSPIM microscope:

https://www.youtube.com/watch?v=7YiQ-8tjYz0

Please note, I have no commercial interest in this product by ASI.

There used to be another small company called AFOptical (no commercial interest) that specialized in optical components that were easily used in a vertical building fashion (ideal for microscopes), but I don't think they are in existence any longer. I used the internet "way-back" machine to locate their old webpage:

As a slightly more custom job you could look at the
WOSM. (http://wosmic.org/). Beautiful and extremely stable, designed for
doing single particle tracking working widefield and TIRF.
