There are many materials that light can not travel through which are called opaque objects.
The scientific term for an object that does not let light through is "opaque." Opaque objects do not allow light to pass through them and therefore block the transmission of light.

Opaque materials do not let light pass through them; they block or absorb light instead. This is because the atoms and molecules in opaque materials are closely packed together, preventing light from passing through the material.

The condenser is the part of a microscope that has a hole in it to let light through. It focuses and directs light onto the specimen being viewed, helping to illuminate it for observation.
An object that does not let light pass through is described as opaque. This means that it blocks the transmission of light, resulting in no visibility or transparency.
An object that does not let light pass through it is called opaque. It absorbs or reflects light, preventing it from transmitting through the object. Examples of opaque objects include wood, metal, and walls.
Materials that allow light to pass through them are called transparent materials.
