light-tight
No rays enter
Light-tight describes something that allows no light to pass through or around it.
The term appears most often in photography, where film and developing equipment must be protected from unwanted exposure: a light-tight darkroom, a light-tight film canister.
Also applies to scientific instruments and optical equipment requiring complete darkness.
