This is also possible but less likely with metal film and wirewound resistors.

Thin metal films are also seen as a potential replacement material.

In the Kretschmann configuration, the metal film is evaporated onto the glass block.

The light again illuminates the glass block, and an evanescent wave penetrates through the metal film.

This emitted light can be detected behind the metal film from various directions.

They are produced from thin foils or metal films.

Then you apply an evaporated metal film to the substrate.

Looking inside, I saw a small metal film can.

Such a device can be used to study the quality of electroplated metal films or to investigate corrosion as it happens.
