Primarily three:
-Magnifying glass
-Wood’s lamp: A fluorescent and long-wave ultraviolet light that has been narrowed to 360 nm.
Developed by Robert Wood (1868–1955), it is commonly relied on for detecting fungal lesions,
areas of hypopigmentation, and porphyrin compounds. In a darkened room, it reveals fungal
infections (like tinea capitis) as sharply marginated patches of bright blue-green. Since melanin
absorption is at 360 nm, it also identifies areas of vitiligo or tinea versicolor (hypopigmented patches as
pale-white, and depigmented areas as bright-white). Finally, it makes porphyrin compounds stand out as oral red fluorescence, like in erythrasma, a bacterial infection of intertriginous areas (axillae).
-Scalpel: To get scrapings for fungi or arthropods (scabies)
