Wood's lamp
Dermatologist's UV light
A Wood's lamp is an ultraviolet light used to examine skin, hair, and bodily fluids.
Under its glow, certain fungi, bacteria, and pigment disorders fluoresce distinctive colors invisible in normal light.
Dermatologists use it to diagnose conditions like ringworm and vitiligo.
Forensic investigators use it to detect biological evidence at crime scenes.
