fotonimittauslaitteet
Fotonimittauslaitteet, often translated as light measurement devices or photometers, are instruments designed to quantify the intensity of light. These devices operate on the principle of converting incident light into an electrical signal that can then be measured and displayed. The core component of most fotonimittauslaitteet is a photosensitive element, such as a photodiode or a photomultiplier tube, which exhibits a change in its electrical properties when exposed to photons.
The output signal from the photosensitive element is proportional to the amount of light it receives. This
Fotonimittauslaitteet find widespread use across numerous fields. In photography, they are essential for determining correct exposure
