Re: Test wafer distribution: Many features, includes res chart

Oops! :shock: I didn't look very closely when I opened the envelope, and had forgotten it was one chip to start with. They're not quite as bad as Rik's, but nevertheless in 10 pieces!

The envelope didn't look badly damaged, but it's curved a bit like it went through a roller during sorting.

Re: Olympus BX40 TL mounting problems

I'm not sure why your TLU has a small dovetail, unless Olympus made one for the BH-2 series (without the "U" prefix maybe?) I don't know about. Some of the BH-2 parts had the "BH2" as part of the actual designation but it wasn't put onto the part itself. The U-TLU is a BX series component designed t...

RogerC, I'm going to suggest you put your camera down for awhile and spend your time researching this stuff. Photomicrography is relatively easy. Good photomicrography is relatively hard. Great photomicrography is time-consuming, expensive, and really hard. It's a lot easier that it was in the film ...

With my BHS, I use an NFK 3.3x along with the U-PMTVC 0.3x adapter for my Panasonic GH4 micro 4/3 camera on a C-mount. It gives the equivalent total magnification of ~1.0x, the same as direct projection, but with the necessary color corrections. It's much closer to the right size than the 2.5x which...

Check the position of the prism position push-pull control rod on the right side of the head. It has three positions, one is all image light to the eyepieces, one is split eyepieces and trinocular port, the last is trinocular port only. You're probably on eyepieces only.

Motorized Microscope Stage use for video

I'm considering getting a motorized stage and joy stick and am curious to know how sensitive and smooth I can expect one to be in panning. I would like to be able to chase moving subjects using the joy stick, so the system needs to be smooth, easily and rapidly variable in speed to that I can pan in...

I'm pretty sure I have a Photomicro Adapter L I can part with. It will be late tomorrow or Friday before I know for sure. It should be at my lab and I won't get back there until then. I don't want to tell you I have it for sure, until I have it in my hand! How about half what the other one is listed...

How do you clean the potting material off the chip to expose the circuitry?
