Re: Calcite

Thanks. It turns out that Amazon has an Indian source with lots of tiny, cheap, chip diamonds.

Re: Calcite

Your micro-diamond chip looks pretty cool to me. Any idea where I could get one? They'd likely be a hit for kids in our local Micronaut program.

Re: Calcite

Beautiful results - both on rebuilding the microscope and the images. They likely have you grinning ear to ear after all that work.

Re: What camera adapter for trinoclear microscope

At present I see your photos are listed as "not downloaded yet." That said, your 1/1.8" sensor size should do OK with around a .5x reduction lens fitted ahead of a C-mount camera (if that's how your camera is mounted). That assumes your AmScope microscope doesn't already have a photo relay lens in t...

I've known Robert only through this forum, where his keen mind, careful explorations, and generosity shone through. I hope his family and closest friends take solace in his life and legacy.

Re: Olympus BX51TF as my first microscope - too much?

It would help to know what you want to view -- and also the importance of photography. The scope strikes me as an OK deal IF you need that assortment of optics. The ergonomic binocular head doesn't provide a means of adding a camera. The intermediate piece below it looks to be part of a teaching hea...

Re: Safe objective cleaning solution -- so much conflicting info online?

It helps to have an idea of what the contaminant is to begin. That way you're not always escalating through various attempts, wiping across the lens and its coatings. I inspect with an illuminated magnifier. As everyone suggests, the dust goes with a blast of low pressure air. While I keep a big bul...

Re: Leica M series 50 mm thread?

Which Leica MZ do you have? The MZ6, which is a pretty direct descendent of the Wild M3Z, M7 etc. should fit your RAF adapter if it has an M50 x 1mm thread. Later (larger zoom ratio) Leica CMO scopes use a larger thread. There were some early Wild objectives for the M3 that had an M50 diameter, but ...

Re: Nikon - DIC +

Rafael, I have a somewhat related question. Do you or others know of a source that lists all the DIC prism sliders that Nikon made for its first-generation Eclipse DIC (the one with L-M-H prisms in the C-CU condenser)? I've never seen either a PA10 or PA20 prism - only the PF10 and PF20 - as an exam...

Re: Nikon Microphot DIC

I'm not aware of a service manual. In one case, I stripped out all the (to me) obsolete film camera electronics and turned a Microphot FXA into a manually operated scope. Most everything left, in terms of mechanisms and cleaning, was pretty straightforward. The only complications were packing a new ...

Re: Nikon Microphot DIC

My recollection is that you can get a half-decent DIC effect through some combination of dropping the condenser and slightly offsetting one of the DIC prisms. It wasn't completely even, but useful. Early Olympus DIC systems had the 10x, but omitted the 20x prism. Given a choice, I'd prefer having th...
