Nikon MPlan 60x ELWD NA 0.70 objective

Post by NikonUser »

I used this objective to photograph the shell of a Ostracod, last image:
viewtopic.php?f=27&t=43360
The image was poor.
Thinking that maybe the poor result was more the nature of the subject than the quality of the lens. The shell was strongly convex.

Used the same lens to photograph the scales from a moth's wing (Noctua pronuba)
With the D720 the FOV is 24 mm, at 60x the image was 0.4 mm wide; top image.
The moth scale, bottom right, clearly shows several veins, pale, with clear membrane , black, between the veins (bottom image)
Each black and pale band is approx. 0.001 mm wide.
I'm happy with the objective!

” I suppose you are an entomologist ? “
” Not quite so ambitious as that, sir. I should like to put my eyes on the individual entitled to that name.
No man can be truly called an entomologist,
sir; the subject is too vast for any single human intelligence to grasp.”
