SCALES OF BUTTERFLIES, STUDIED WITH A BRIGHT FIELD MICROSCOPE

All images displayed on this page have been taken with a 100x-objective, oil immersion. The limited resolution prevents an adequate analysis of the structures between the grooves.

100x04 100x06 100x08


The photos beneath have been taken using a green interference filter. They have been converted to stacking images, stereo-pairs and anaglyphs using the program PICOLAY. Width of image: 60 um.

MALINOL MALINOL NAPHRAX
   
NAPHRAX PLEURAX    

PLEURAX has a higher refractive index than NAPHRAX, but it seems to be not the best choice here, perhaps because of higher dispersion.

How to use the stereo-pairs:

Look at the images using a "comfortable distance". Then squint willingly. Between the two images emerge two more overlapping images; suddenly, with a "click", these images merge to a 3D-image which hovers between the stereo-pair. At the same time your brain locks the axis of each eye in such a way that you can look at the 3D-image without any stress, even if you move your head.
