Microscopy вђ Diatom Test Slide By Meakin Jmc Scientific о The one i’m sharing today was by samuel henry meakin and was made in 1945. it is a diatom test slide with examples of a variety of different species. images were taken on my modified olympus bhb microscope, and using a range of different objectives (4x zeiss planapo, 10x olympus uvfl, 20x olympus splan, and 60x olympus splan apo). The john barnett slide is actually paper wrapped, and the diatoms are in the middle of the glass in the centre of the slide. they are of course not visible at this scale. next we have the klaus kemp slide. klaus kemp 7 form test slide. the klaus kemp slide is a simpler affair, and the diatom are inside the small ring in the middle of the slide.
Microscopy вђ Diatom Test Slide By Meakin Jmc Scientific о These images were done using my modified olympus bhb microscope, and have been reduced in resolution for sharing here (the original are much higher resolution). edit, 18th march 2024. i have managed to find an example of one of the diatoms am looking for – truania archangelskiana – on a strew slide i had, so have included an image of that now. This work is a journey into the past up to the present day, along with a set of experiments to understand how microscopy has evolved, thanks to a small part of the many antique, vintage and high end modern microscopes kept at diatom lab. fig. 2a: the diatom test slide version 2.0 by diatom lab with its five selected, micromanipulated diatoms at.

The diatom test slide version 2.0 is a high end test microscope slide that contains 5 cleaned, selected and micromanipulated diatom species (diatoms) with striae, areolae and poroids that can be resolved or detected through a light microscope. it is extremely useful to<br >a) compare objectives, condensers, microscopes and optical microscope illumination techniques such as bright field.

Metalizing slides of diatoms to boost contrast is a technique which has been around for over 100 years, and variations on the technique still live on today. probably the most well known practitioner was horace dall (an optical genius and someone i’ve written about before on this site), however the slide maker john dale is also known for making high quality aluminium coated diatom slides.
