Re: Loss of Robert OToole

I can't believe the loss of Robert. If anyone represented unlimited generosity to help and make the world of macro and micro known to the rest of the world, it was Robert. I think he was the most well-known person in our micro world. His incredible tests and discoveries of all types of lenses, objec...

Re: fs: Olympus CX23 trinocular microscope new

You can use this as a price reference: I sold mine for $2300 AUD. Mine has the 100x oil immersion objective which I purchased afterwards, and I tossed in some goodies for free. It took several months to sell, a histopathologist purchased it to work from home. I would like to buy a time machine so I...

Re: Iridescent crystalline nanostructures on the leg of Eupholus schoenherri weevil (60x)

Iridescent crystalline nanostructures on the leg of Eupholus schoenherri weevil (60x)

Photonic crystals are periodic nanostructures that selectively interact with light. In weevils, these crystals are found in their exoskeleton and are responsible for their iridescence, exhibiting brilliant and changeable colors. These crystals are composed of alternating layers of chitin and air, wh...

Re: Nikon Small World eligible lenses

I work a lot with my Minolta 5400 lens, but objectively I think that its use cannot be considered to participate in the Nikon Small World contest The rules say that the images must be taken by the participant using an optical microscope, therefore the mandatory use of a microscope lens, even if it i...

Re: Mitutoyo 20x/0.42 compared with workalike Hoopuo 20x/0.45

I activate this thread that I found very interesting
How is the Hoopuo 20x/0.45 sales going?
Has there been further testing?
Will it be possible to get some well-tested copy from the factory that works like the one in the test of Chris S.?

Re: Shutter speed vs magnification

The solution I think is to use the Live view mode together with the silent shooting option (EFCS) Electronic Front-Curtain Shutter
