Thanks. If you are particularly interested in polarisation you will get better results for high magnification imaging using the newer 'Uber pol' attachment to the standard PUMA Abbe condenser described in this video: ruclips.net/video/80MFESeIbnc/видео.html . Keep an eye on the channel for further update videos for the latest mods and upgrades.
The main issue with PUMA microscope is there is too many parts and it feel fragile/unstable or not easy/quick to adjust or not reliable to use. Not to mention so many parts to buy (and possible mistakes). I know we can buy bundle from you, but with the shipping, it's still quite expensive. If we really need a great but basic field microscope on a budget, we can find them under 300$. Sure, for +2000$ model, DIY start to make sens. But why getting them so weak/flimsy? Don't get me wrong, PUMA is amazing and the video quality/explication is still the best I've seen (after 2 years looking way too many video on the topic). My dream DIY project... Inspired by the sexy but outrageously expensive ECHO REVOLVE I was thinking about printing a large hollow base, then fill this base with concrete. It create a very stable/stiff, efficient and cheap base. It can be 2-3 large concrete part that will anchor smaller module or more fragile part. It can be overkill with 20lbs of concrete or just few pounds for a sturdy but still portable unit. I was thinking only one eyepiece with phone camera mounted on it. It would keep cost low and quality high. Plus direct observation is not comfortable compare to screen. And video open the computer treatment of image, etc. I think concrete base + PUMA technology + phone camera could be the perfect mix. I know it will still need lot of parts to make it adjustable and lot of time... So... maybe one day I'll do it. The other option will be to start with a cheap but great quality scope and hack it to add more technology. Last week, I've changed my mind (not going DIY from scratch) when I saw an amazing deal on a SWIFT380B microscope for 203$ (canadian, shipping next day, from Amazon.ca/Swift official. New open box) regular price 299$ canadian. I already had 4x, 10x, 40x, 60x semi-plan objectives and a 40x for fluorescence total price for theses 5 items: 75$ canadian (new). I will thinker with my 3D printer on this already working scope (darkfield filter, polarized filter, basic fluorescence, DIY optic fiber illumination for top, phone camera adapter and so on. I'm curious to know your thought on my ideas and positive critic of PUMA. Sincerely yours, Alexandre Valiquette, from Montréal
Hello, Re 'many parts' - I do agree, but there is a reason for that. Also, this, plus the time and work involved in putting it all together is why is costs so much to buy (instead of make DIY) - so can't compete with off-the-shelf prices for mass-produced standard scopes like of Swift. Re 'flimsy' - I respectfully disagree. Don't get me wrong. PUMA is not a stable heavy metal desk scope - I do admit that in the videos - but then it was not intended to be such and, furthermore, you can stabilise it to a desk and use the stabiliser module to increase stability as I demonstrate in my video on the stabiliser here: ruclips.net/video/d8tMtWFhNY4/видео.html ). However, PUMA is not primarily designed for people who 'just want a cheap small scope' - if that is your goal then sure, I agree it would be better for you to just buy a standard scope. PUMA is for those who need many options and complete customisability (not just modding the condenser of a Swift to give you dark field) and portability (so that rules out Echo revolve). For example, the Köhler Fourierfeldblende projection, augmented reality, Z-motor, epi-illumination in bright or fluorescence, epi-polarisation and trans polarisation, coherent light microscopy, etc. - these modular options, and more, can all be bundled into a little light bag with PUMA and taken along on your journey. This is something you can't do with a Swift or similar - but then if you don't need any of those things with ultraportability, then you don't need PUMA. Also, PUMA is for teaching and learning about how microscopes work and for experimentation with new designs and optical modalities - like interference microscopy, structured light illumination, superresolution microscopy, etc. (which I have not done videos on yet - but keep watching). Regarding a heavier base, I did consider making an extra stable base option but not to be filled with concrete (most people would not want to work with that,. esp. in small quantities), but rather a 3D printed stand with a base that may be filled with wet sand or clay or pebbles (whatever is out in the field where you are working) so you can have a heavy base on site without having to carry the heavy weight along with you on your travels - just empty the base container when you finish and move on to the next site with a nice light scope in your bag. I am also working on a more stable base for XYZ precision motor-controlled microscopy - more of that to come. Remember PUMA is not just a standard microscope made with 3D printing and DIY - think about what each of the letters mean and put them all together. How many of the other scopes you mention have all those things (P. U. M. A.)? But not everybody needs or wants those things - so, for sure, PUMA is not for everyone. Thank you for your comments. PJT

Oh this is fantastic! I definitely have to build this system. Thank you for sharing :)
