Optics / Re: Re-use of GRIN lenses

« on: June 23, 2017, 04:22:47 PM »

I have been trying to clean GRIN lenses for reuse and even after multiple soaks in acetone they seem to still have a little bit of dirt visible on them when examining them under a dissecting scope. I've tried using lens paper with acetone and lens cleaner and still find it hard to get them looking like new. Do you find that this small amount is acceptable for imaging or is there some other step or method you use to additionally clean this last little bit of stuff off before reimplanting them?

Thanks

DAQ Software/Firmware / Re: mscam retrieval error, possible driver issue

« on: May 12, 2017, 03:34:20 PM »

Thanks for your response. I have tried uninstalling the driver and manually choosing and installing the one you provide but the computer won't do it. I can see the driver in the folder, but when I point to that destination I get an error that there isn't an appropriate driver in that location.

If we were to buy a new laptop just for the purpose of running the miniscopes what you recommend? Sounds like you use some version of a Macbook running Windows 10? I might prefer to just get exactly what you guys use to avoid these kind of issues.

DAQ Software/Firmware / mscam retrieval error, possible driver issue

« on: May 10, 2017, 07:40:53 PM »

I am hoping to get some help figuring out the cause of my mscam retrieval errors. All three LEDs on the DAQ box are lit and do not flicker. I am able to connect the software to the scope successfully every time and adjust gain or led power just fine, however after some time (ranging from just a few seconds to 5 minutes or so) I get the frame retrieval error and the software crashes. After reading all the similar posts on the forum I assumed it was the soldering on the CMOS pcb or the coax connector. Redoing all the soldering and even trying another CMOS pcb didn't change anything. I am using a brand new Dell laptop with windows 10 so I didn't suspect that could be an issue, but eventually tried an older desktop we have running windows 7 and everything works perfectly on that computer. I tried connecting a number of times without problems and even left the scope running for over an hour without crashing. Does this mean I have a problem with the drivers on the new laptop? Any other possible suggestions?

Also, I am using the short amazon USB 3.0 cable you recommend and the USB ports are definitely 3.0 on both computers.

Thanks

Does this order include them sourcing the CMOS imaging sensor along with the other components?

Thanks for organizing this. Any idea when this order will be submitted and about how long they will take to be delivered after that?
