Has anyone any experience of these microscopes?

My workplace has one (don't know witch), it is satisfactory. Might be
nice to be able to save the image is USB or something - but otherwise no complaints about optics, image quality, or build.

I have one from Mustool, I'm not sure what model it is.
I find it gives a good image and is useful for inspecting boards, although I suspect a binocular microscope would be superior.

I have a Mustool G1200. As others have suggested, they work well for what they are, though a proper optical binocular scope would I am certain be way better. My variant has the ability to save photos or video to microSD. It also has a rechargeable battery. There seems to be a bunch of different variants, so just be aware of that when comparing prices. One thing I still plan to add to mine are some small gooseneck mounted side lights. I find the ring light can do an excellent job of washing out any markings on an IC, but if you hit it with light from the side it appears just fine. I have a few Ikea Jansjo USB gooseneck lights that I plan to use for this. Just haven't had the time to build it...yet!

I've also found choosing the colour of the light from the side can make a big difference. I keep a few red, green and blue LEDs handy with a CR2032 for this purpose. -- James Cameron http://quozl.netrek.org/ -- http://www.piclist.com/techref/piclist PIC/SX FAQ & list archive View/change your membership options at http://mailman.mit.edu/mailman/listinfo/piclist |

Thanks James, different colour LEDs are a good tip.

I've not had to do it yet, but on my list to try is UV and IR leds.
Microscopes with CCDs and very few lenses in front of them may not have effective UV and IR filtering, because it isn't needed in the application. The bayer mosaic integrated into the CCD is an optical band-pass filter, with frequencies chosen for human eyesight peaks. The red and blue filters don't necessarily need to constrain themselves at the IR and UV end of the spectrum. -- James Cameron http://quozl.netrek.org/ -- http://www.piclist.com/techref/piclist PIC/SX FAQ & list archive View/change your membership options at http://mailman.mit.edu/mailman/listinfo/piclist |
