Lovibond Photometers used for measurement purposes in science laboratories

Photometers are important lab equipment used in science experiments to measure the intensity of light from a particular source. The principle of measurement followed by these devices is to compare the illumination produced by an unknown source to that of a standard source and calculate the intensity of light accordingly. Various photometers use different principles to operate. Selection of a source should depend on the accuracy you desire and the type of source that is commonly being studied. Spectrophotometers and filter photometers are the two most common types of photometers being used for measurement purposes in science laboratories. These have prisms or optical filters within the
