The eyepieces ... are identical, but ... differently aligned when mounted.... I can't get both in focus at the same time at the same distance.... --- End quote --- What Amscope model is it? If you do not know, could you post a side view of the head that shows the eyepieces and eyepiece tubes? Different microscopes have different ways of getting sharp, stereo images. |

Always right eye that comes out blurry. Switched the lenses, and still right eye blurry. Always in the end of the range when it come to adjust it clear. It's a strange thing, using på right eye on the left side of the scope, it's clear with both lenses! Must be a fault in the Amscope itself. If I get down to my lab , I will take some photos. --- End quote --- Why wouldn't you have contacted amscope about the issue.. clearly its not supposed to be blurry. I assume you know how to adjust the focus https://www.microscopeworld.com/p-3359-how-to-adjust-focusing-microscope-eyepieces.aspx --- End quote --- I've had an Amscope for a while, I think same or similar to this one https://amscope.com/collections/stereo-microscope/products/zm-4tn3 but I've never been able to get it to stay in focus across the different zoom levels (have to refocus after change zoom levels) is that normal or am I doing something wrong? |

Have you tried the usual procedure to make the microscope parfocal? From the microscope manual for the Meiji Techno EMZ, an original that Amscope may have copied: --- Quote ---It is necessary to adjust, so focus remains sharp through the whole range of zoom magnification and so that the image is seen equally sharply focused in both right and left-hand eyepieces. (1) Set microscope magnification to the highest power 4.5X by turning the zoom control knob counter- clockwise. (2) Then focus sharply on the specimen. (3) Set to the lowest magnification by turning the zoom control knob clockwise. Do not touch the focusing controls. (4) Looking with the right eye through the right-hand eyepiece, turn the eyepiece’s dioper adjustment ring until the image is precisely in focus. (5) Do the same with the left eye and left-hand eyepiece. (6) The fused microscope image should now be uniformly sharp throughout the zoom range and without refocusing. --- End quote --- |

Erik, I saw you mentioned that you refrain from using products from china, but I must say that both the Amscope and the small head mounted loupe are excellent products that help me immensely. The Amscope took me a bit of time adapting to it, but I had to properly adjust its oculars: first, close the right eye and put the object in focus with the normal focus control, then close the left eye and adjust the small ocular to rule out any eye differences. It has seen most use for inspections and large soldering jobs on boards. The model is SM-1TS-V203 and I show it in this video (in portuguese only, sorry). The loupe has been seeing more action lately due to my work on radio chassis and in the attic. Although it is not as light as my dad's old loupe, it has great cushion, us adjustable and allows combining two lenses for extra magnification. The kit comes with a wide selection of very thick acrylic lenses (glass would have been even heavier). This loupe also has three LEDs powered by three AAA batteries. Although I thought it could have been a gimmicky feature at first, it has helped me immensely in illuminating the work I am doing at a given time, especially because the light focus can be positioned independently from the head position. The model itself is unknown but the description to this video has the store that I bought it. Good luck in your search! |
