Phase
Contrast and COL combinedIt occurred to me that since the imagery
raised through the employment of full aperture annuli in COL has
subdued tonality, but very high resolution, www.microscopy-uk.org.uk/mag/artnov07/pj-condenser2.html
Circular
Oblique Lighting (Part 1)Technically speaking it is 360 degree Oblique
Illumination OR Circular Oblique Lighting For brevity's sake I shall
refer to it as COL illumination www.microscopy-uk.org.uk/mag/artdec02/pjcol.html
Off
Axis COL UpdateThose who have taken to COL lighting techniques will no
doubt have developed it to their own satisfaction by marrying substage
annuli to suitable objectives www.microscopy-uk.org.uk/mag/artmay08/pj-colupdate.html
Circular
oblique lighting (COL) Part IV: updateI have been constantly impressed
with COL, and especially with the humble achromat: the performance of
which seems to be particularly elevated in comparison www.microscopy-uk.org.uk/mag/artoct03/pjcol4.html
Circular Oblique Lighting Part 2It must be emphasized that there is no definitive COL set-up, www.microscopy-uk.org.uk/mag/artjan03/pjcol2.html
