#138 and
#139 combine the font from #64 with the mark from #65.
#140 shows a blue "circle" inside the "o" in geolenz. I don't think the blue next to the orange works so well, so #141 shows a separation between the two. It's a great thought -- to connect the wordmark to the graphic, but the "o" in that font isn't perfectly round like the lens in the graphic. So #142 shows a modified wordmark with a completely circular "o" and separation between the colors -- plus I took it a step further and recolored the wordmark so that the inside circle is the same color (orange) as in the graphic.
Thanks so much! Don't hesitate to let me know if I can make more revisions.
