emits UV light to diagnose skin and hair conditions
A Wood's lamp, also known as a Wood's light, is a diagnostic tool that emits ultraviolet (UV) light. When shone on the skin or hair, it can help identify fungal infections, bacterial infections, and pigmentary disorders by causing affected areas to fluoresce in distinctive colors. This tool is particularly useful in dermatology for diagnosing conditions like tinea capitis (scalp ringworm) and vitiligo.
