| 0.7x Barlow Lens for this Stereo Microscope possible? |
| (1/2) > >> |

Hi. I needed stereo microscope for soldering work, and got this used one: It has WF10X eyepieces and switchable 2X and 4X objective, you rotate it 180deg to select. Now I read everywhere that I'm better off with 0.5x or 0.7x Barlow Lens at the bottom, to reduce magnification and increase working distance. Most common barlow lenses have 48mm diameter screw-on threads. But this scope has no threads at bottom, see "Pic 1", was a bit of disappointment. What do I do? Much appreciated! |

That looks to me like a typical, 10X/20X dissecting microscope. Here, is an ad for the one I have, I bought for cheap to learn on, that shows a typical use and user: (Looking at her hands and makeup, I would say that is an older model posing as a high school student.) I expect you belong to a different demographic that needs a different microscope, a "routine, system microscope", which you can add to or change – for example, with different stands, eyepieces, barlow lenses, and so on – to address a wide range of applications. |

Yes, typical stereo scope, I'm not in position to buy new AmScope, but I want AmScope :) It seems I have the solution, I bought this 0.3X Barlow lens on Aliexpress with 42mm thread, that I will jam somehow into the bottom of the black plastic conical housing I have, which is 40mm inside diameter at the bottom. https://www.aliexpress.com/item/1005004924531709.html AmScope SM-3 Manual SM-3_Manual_151001.pdf has same barlow lens arrangement (see page 15), which gives me hope. This will reduce magnification from 20x,40x to 7x,14x with increased working distance. Now I need boom-arm stand lol |

That often gives not half bad results because of the low numerical aperture of the barlow lens. Rather than jam, you could glue to the conical housing, a 42mm to something-at-least-as-big camera thread adapter and then be able to add or remove the lens or other accessories. What is the plastic? |
| dredd:
Some plasticky feeling hard plastic :) Maybe has carbon fibers in it. Yea, I heed to find something bigger with inner 42mm thread, it feels like a challenge... |
