Biology, physics, chemistry, microbiology, medicine, forensics, and textile industries are some areas where a spectrophotometer can be used.

What is Spectrophotometry?

We can get an idea of what this is by looking at its name carefully; ‘spectro’ means band of colors, ‘photo’ means light, and ‘meter’ is a device for measuring something.

Spectrophotometer comes in varied shapes and sizes. It looks like a bar code reader, fax machine, or a weighing scale, etc., depending on its size. It can be hand-held or kept on a table just like a printer…
