I cannot recall when I got my 1st SPZ-50 but it was a very long time ago. I absolutely love it the microscope and it&#8217;s optical clarity,\u00a0 smoothness and ergonomics of the controls, is great never an issue with it. A while back I tried an Amscope it was garbage it gave me headache after 30 to 40 minuets of use and the optical distortion was like spearing a fish in water.

I went to invest in a Digital Trinocular Microscope. I have been seeking one of these Aven Trinocular for about 5\u00a0 years and have had it on my search list for about 2 years.\u00a0 I make very little from my YouTube! So I need to be very frugal when obtaining items to bring you content so second hand is generally the way that happens. What I got was a <a href=\"https:\/\/aventools.com\/collections\/aven-designed-stereo-microscopes-systems\/products\/stereo-zoom-trinocular-microscope-spzv-50-6-75x-50x-on-post-stand-with-integrated-light-and-usb-6m-camera\">Aven Tools Part # 26800B-383<\/a> a $4,200 Microscope with Integrated Light and USB Camera.

So I reached out to Aven, well they have been one of the most difficult companies to order parts form. Basically if a part including a replaceable c-mount it is a big &#8220;Fuck You buy another&#8221; They come at you with some shyster used car sales man tactics.<\/p>\n<p>Aven tools and I had a video conference 04\/30\/2025 Mark Kanpurwala &#8220;Mansoor Kanpurwala&#8221; (Director),\u00a0 Mark reassured and promised me that they can get the parts for me and they will send me the proper parts list to get them the part numbers for the parts I need.

Using calipers, a thread pitch gauge, and thread files I was able to cleaning up the threads, and the adapter screwed in smoothly. The result is structurally weak, and the focus point is much too high to achieve parfocal alignment but it successfully demonstrates that the misroscope is repairable if the parts would be made available.<br \/>\n<a href=\"https:\/\/www.stevenrhine.com\/wp-content\/uploads\/2025\/05\/Aven-SPZV-50-SPZV-50E-with-3d-printed-adapter.jpeg\"><img decoding=\"async\" class=\"alignnone wp-image-136494\" src=\"https:\/\/www.stevenrhine.com\/wp-content\/uploads\/2025\/05\/Aven-SPZV-50-SPZV-50E-with-3d-printed-adapter-576x1024.jpeg\" alt=\"\" width=\"281\" height=\"500\" srcset=\"https:\/\/www.stevenrhine.com\/wp-content\/uploads\/2025\/05\/Aven-SPZV-50-SPZV-50E-with-3d-printed-adapter-576x1024.jpeg 576w, https:\/\/www.stevenrhine.com\/wp-content\/uploads\/2025\/05\/Aven-SPZV-50-SPZV-50E-with-3d-printed-adapter-169x300.jpeg 169w, https:\/\/www.stevenrhine.com\/wp-content\/uploads\/2025\/05\/Aven-SPZV-50-SPZV-50E-with-3d-printed-adapter-768x1365.jpeg 768w, https:\/\/www.stevenrhine.com\/wp-content\/uploads\/2025\/05\/Aven-SPZV-50-SPZV-50E-with-3d-printed-adapter-864x1536.jpeg 864w, https:\/\/www.stevenrhine.com\/wp-content\/uploads\/2025\/05\/Aven-SPZV-50-SPZV-50E-with-3d-printed-adapter.jpeg 1152w\" sizes=\"(max-width: 281px) 100vw, 281px\" \/><\/a> <a href=\"https:\/\/www.stevenrhine.com\/wp-content\/uploads\/2025\/05\/Aven-SPZV-50-SPZV-50E-with-3d-printed-adapter-and-C-Mount.jpeg\"><img decoding=\"async\" class=\"alignnone wp-image-136495\" src=\"https:\/\/www.stevenrhine.com\/wp-content\/uploads\/2025\/05\/Aven-SPZV-50-SPZV-50E-with-3d-printed-adapter-and-C-Mount-576x1024.jpeg\" alt=\"\" width=\"281\" height=\"500\" srcset=\"https:\/\/www.stevenrhine.com\/wp-content\/uploads\/2025\/05\/Aven-SPZV-50-SPZV-50E-with-3d-printed-adapter-and-C-Mount-576x1024.jpeg 576w, https:\/\/www.stevenrhine.com\/wp-content\/uploads\/2025\/05\/Aven-SPZV-50-SPZV-50E-with-3d-printed-adapter-and-C-Mount-169x300.jpeg 169w, https:\/\/www.stevenrhine.com\/wp-content\/uploads\/2025\/05\/Aven-SPZV-50-SPZV-50E-with-3d-printed-adapter-and-C-Mount-768x1365.jpeg 768w, https:\/\/www.stevenrhine.com\/wp-content\/uploads\/2025\/05\/Aven-SPZV-50-SPZV-50E-with-3d-printed-adapter-and-C-Mount-864x1536.jpeg 864w, https:\/\/www.stevenrhine.com\/wp-content\/uploads\/2025\/05\/Aven-SPZV-50-SPZV-50E-with-3d-printed-adapter-and-C-Mount.jpeg 1152w\" sizes=\"(max-width: 281px) 100vw, 281px\" \/><\/a><\/p>\n<p>The Camera is an Aven Mighty Cam USB 3.0 6MP, part\u00a0 Number <span id=\"variantSku\" class=\"label-sku\">26100-244 <\/span>Well that is made for Aven by <a href=\"https:\/\/www.tucsen.com\">Tucsen<\/a>\u00a0 it is a\u00a0 <a href=\"https:\/\/www.tucsen.com\/michrome-6-product\/\">MIchrome 6<\/a> also sold on aliexpress under a bunch of different names as well.

My other alternative if a c mount is not available would be to get the T. PRISM BOX SEAT machined to a M28 X 0.75 thread to accept common c-mounts. Machining it would come with a lot of risks an expense. But at the price point of these microscopes we should not have to struggle to get parts as accidents and negligent damage happens it should not condemn the thing to e-waste or become unusable as intended over an easily removable replaceable part that most other manufactures of microscopes at this price point make available.<\/p>\n<p>Why if you are\u00a0 considering lower cost unit buy it, why spend 4 to 5x&#8217;s more on an <a href=\"https:\/\/aventools.com\/\">Aven Tools<\/a> microscope that still cannot be repaired make no sense. I\u00a0 will be calling other manufactures and finding out wha\u00a0 microscope manufacture in this price range is repair friendly.<\/p>\n<p>I attempted to work with Aven but they just did not want to even consider selling repair parts\u00a0 or even provide a simple\u00a0 parts diagram for the proper model.
