undiffused

Kept tightly focused

Undiffused describes light, energy, or other phenomena that have not been scattered or spread out from their source.

Undiffused light remains concentrated and directional, producing sharp shadows and harsh contrasts, unlike the softer quality of diffused light.

The term extends to abstract contexts: an undiffused message retains its original force and clarity rather than being diluted across multiple channels.
