I have been to sites with font identifiers and font matcherators, but in vain. Can any of you help me about the name of this font? It is simple, I can draw that word, but I need more words for the project. It says "OPTIKA", if that's needed.
One doesn't see in this exactly what and where you've tried - please review this canonical question which explains GDSE font-match question criteria:
Seems to me that both Churchward 69 and Moog are very similar (assuming a significant vertical scale compression having been applied to your sample) and the further differences I see in the lowercase t could well be vector editing differences of a bespoke logotype.
Hope this helps some.
