Liquid level monitoring inside plastic bottles

How can a pharmaceutical company assure that medicine bottles are filled to the proper level? Medicine bottles are often made of frosted plastic making accurate visual detection difficult

How can a pharmaceutical company assure that medicine bottles are filled to the proper level? Medicine bottles are often made of frosted plastic.

The purpose is to protect the contents from degrading when exposed to light, a similar problem to that of fabrics fading in sunlight.

The problem is that the bottles are opaque when viewed by the human eye or with a standard silicon camera, making it difficult to confirm or guarantee proper filling during production.

The use of a Sensors Unlimited shortwave infrared (SWIR) camera makes it easy to see and monitor the liquid fill level in a standard opaque bottle.
