    Optic microscopes. New illumination technic

    Dark field? Similar but not same. Hi Drakkith That is what the mathematic model predicted. A dark field. However there are some differences from standard dark field. First, the background should be dark, yet , it is not. Check out dark field photos. Be well

    Optic microscopes. New illumination technic

    Hi Andy Thanks for commenting. Claimed advantage? Well, I don't know yet. But this is what I can say: Although the field of view is different; it is the same specimen. From Physics / light / Optics / Microscopy point of view we can see the following: - At bright-field we have mainly refracted...

    Optic microscopes. New illumination technic

    You are correct. I am being egoistic since I cannot publish yet. And the purpose of the post is to know if you people find it interesting. Just out of curiosity. I will submit full article once I end development of device. I had qualms before posting for the very reason you mention. Yet I did...

    Optic microscopes. New illumination technic

    Dear friends I have been working on a new way of illuminating microscope specimens. Cannot disclose the innings of it since all is under development. Nevertheless I attach photo since I think you will find it interesting. That is the mouth of a honey Bee, photo compares standard bright-field...

    Total internal reflexion on a polymer

    Dear Bob THKS a lot. Using a viscose fluid was my first though owin to the need of enhanced contact. But I didnt know glycerine was the appropriate one, big thanks. I have to check the possible interations between the paint of the artwork, as you pointed out. lets see how it turns out...

    Total internal reflexion on a polymer

    Dear Everyone I am facing the following engineering problem. I "inject" light in a flat (6.5mm) Acrylic panel at the edges of it. Due the different refractive index of the Acrylic material (1.4) and air (1) 90% of the "injected light" experiments total internal reflexion. I need to get the...
